Five suspects are in federal custody after the FBI and its law enforcement partners disrupted what officials describe as a multi-phase attack plan targeting the UFC Freedom 250 event on the South Lawn of the White House, a scheme that allegedly called for explosive-laden drones, a pre-staged sniper team, and a second wave of attackers storming the White House gate.
The alleged plot, which Fox News Digital first reported, was disrupted before it could be carried out. The FBI said it first learned of the threat on June 10, just four days before the June 14 event, after the mother of 19-year-old suspect Tycen Proper contacted authorities about her son's recent firearms purchases and his online communications with strangers.
That single tip from a worried parent set off a sprawling, multi-state investigation that stretched across at least 12 FBI field offices. By Monday, five people were in custody. Investigators had identified 23 individuals communicating through the encrypted Signal messaging app, allegedly discussing what court documents describe as pre-operational planning for the attack.
The scope of the alleged conspiracy is striking. Court filings describe a layered assault: explosive-laden drones would hit buildings near the event, triggering a mass evacuation. As thousands of panicked attendees fled, a pre-positioned sniper team would open fire on the crowd. A second wave of attackers would then storm the White House gate.
An estimated 4,300 people attended UFC Freedom 250, including roughly 1,200 active-duty service members. Fourteen fighters from around the world competed at the event, which President Trump hosted as part of his 80th birthday weekend.
One suspect allegedly told investigators the goal was to target "capitalist elites," "billionaires," or politicians who had received donations from the American Israel Public Affairs Committee. The AP reported that the plotters were united by anti-government conspiracy theories and anger over the Epstein files.
The question of how to protect high-profile events at the White House has taken on new urgency in recent months. Congress has wrestled with White House security funding provisions even as threats to the executive mansion evolve.
The suspects arrested so far span the country. Tycen Proper, 19, was taken into custody in Cincinnati. A criminal complaint states he allegedly spent $3,000 of his "graduation money" to purchase ammunition, guns, extra magazines, and other equipment for the alleged attack. Authorities recovered an AR-style rifle, a bullpup rifle painted with an American flag, two plate carriers loaded with AR-style magazines, and several boxes of ammunition, estimated at thousands of rounds.
Proper's father told officers his son had quit his job to meet up with people he had connected with online to conduct "missions" and "recons." His family voluntarily turned over the equipment to law enforcement.
Bryan Omar Roa and Michael Alan Thomas were arrested in California and appeared in court Monday in Riverside on charges of conspiracy to commit murder. Daniel K. Eskridge, of Kansas City, Missouri, was also arrested. Court documents state that Eskridge's wife told investigators he described himself as a recruiter for the group. She became aware of his Signal communications through messages that appeared on a shared tablet. Eskridge had allegedly amassed tactical gear, including a rifle and ammunition, in recent months and built a firearms range on his property roughly three weeks before his arrest.
The fifth suspect, Abraham Hermosillo Alvarez of Omaha, Nebraska, allegedly operated under the online moniker "Shepherd" and served as a key organizer. Court documents describe him using Signal to direct staging locations, sniper and drone positions, escape routes, and communications protocols. He allegedly discussed coordinating with other groups and urged participants to obtain additional explosive-capable drones, writing: "As many and as deadly as we can get."
Some suspects allegedly planned to travel to Fredericksburg, Virginia, on June 12 or 13 to prepare for the attack. The investigation began after a search warrant was executed in Cincinnati on June 10, the New York Post reported.
FBI Director Kash Patel credited the speed and coordination of the response in a statement to Fox News Digital:
"Thanks to the rapid action of this FBI, our partners, and the Department of Justice in a multi-state operation, multiple individuals are now in custody and allegedly planned attacks were stopped cold."
Patel added that the result "represented the best of investigative work" but was "also nothing out of the ordinary for this law enforcement team." He said the FBI is "built to detect, respond to, and bring to justice those who threaten the lives of American citizens, particularly during large gatherings like the historic UFC 250 fight."
Secret Service Director Sean Curran said his agency's personnel "worked around the clock to identify those responsible and hold them accountable." He added that formal comments on the case specifics would come through court filings. A joint FBI-Secret Service statement declared that the investigation "highlights that continuous partnership" and warned that "if you target Americans, you will be found and brought to justice."
There were signs of friction behind the scenes. Senior U.S. officials described USSS leadership as "disappointed" with the FBI for making its announcement Tuesday morning, suggesting there had been a plan to coordinate the timing of the public release. The joint statement appeared to smooth over any rift.
Ongoing debates about the Secret Service's institutional structure, including a bipartisan bill that would pull the agency out of DHS and place it directly under the White House, add context to the interagency dynamics at play.
Retired FBI agent Jason Pack told Fox News Digital that the alleged conspiracy had moved well past online rhetoric. He called it "a real threat" and described it as "organized political violence with specific targets." The plot was stopped, Pack said, because of human intelligence, a family member who saw something wrong and picked up the phone.
"That's how this got stopped," Pack said.
The distinction matters. Investigators found at least 23 Signal users discussing pre-operational activity after examining one suspect's iPhone. Five are in custody. The status of the remaining 18 individuals in the alleged network remains unclear, and the investigation is ongoing.
Vice President JD Vance, appearing on "FOX & Friends" Tuesday, called the alleged plot "very, very dark stuff" and pointed to a broader pattern. He said the incident is "what happens when people turn the rhetoric up so loud that disagreeing with somebody is a cause for violence."
"But I think a lot of my Democratic colleagues in Washington have got to look themselves in the mirror and say, why is so much of this political violence coming from our side of the spectrum?"
Vance also noted that the plot "didn't even get close to the point of execution", a point that speaks both to the early stage of the conspiracy and to the speed of the law enforcement response.
Several questions remain open. Specific charges against Proper, Eskridge, and Alvarez, beyond the conspiracy to commit murder counts filed against Roa and Thomas, have not been publicly detailed. The identity or affiliation of the outside groups Alvarez allegedly discussed coordinating with is unknown. The type of explosive-capable drones discussed or obtained has not been specified. And whether additional arrests are forthcoming from the broader 23-person network is something the FBI has not addressed.
Physical security at the White House itself has been a running source of political dispute. A federal judge earlier this year blocked construction on the White House grounds that the administration had justified partly on security grounds. Meanwhile, six Republican senators sided with Democrats on a separate proposal related to White House construction, a reminder that even within the GOP, consensus on hardening the executive mansion has been elusive.
The alleged plot against UFC Freedom 250 did not succeed. But five suspects in custody, 18 more names on a list, encrypted chats full of operational planning, and a 19-year-old who spent his graduation money on rifles and plate carriers tell a story that should unsettle anyone paying attention.
A mother's phone call to authorities is what stopped it. The question lawmakers and law enforcement need to answer next is what stops the one where nobody calls.
