An Ohio man accused of plotting a terrorist attack at the White House during the UFC fight had built up a stockpile of weapons, ammo, and more, according to authorities.
Tycen Proper, 19, is one of the seven men accused of plotting an attack at UFC Freedom 250 at the White House, which took place on June 14. Officials said the FBI first learned about the attack plot on June 10 and worked with local authorities to make the arrests.
A report released by the Knox County Sheriff's Office in Ohio indicates that Proper spent $3,000 on armor, vests, a shotgun, extra ammo and also obtained other supplies.

Officials alleged Proper had stockpiled the two firearms — an American flag-painted 12-gauge semi-automatic shotgun with a red dot optic and an AR-15 rifle with a red dot sight and magnifier — along with three plate carriers loaded with .308-rated ballistic plates, a tactical bump helmet, a battle belt with loaded ammunition pouches, 13 loaded AR-15 magazines, more than 1,000 rounds of 5.56 ammunition, dozens of 12-gauge shells including buckshot and rifled slugs, multiple fixed and folding blades, a hatchet, two tactical headsets, chemical lights, compass, and extensive medical trauma gear including tourniquets, emergency bandages, wound seals and gauze — all stored at a family member's home.
Proper spent $3,000 of his "graduation money" to build the stockpile, according to a criminal complaint.

His father told law enforcement that Proper quit his job in order to meet up with people that he met online, who conducted "missions" and "recons" together, according to the complaint. Proper's mother alerted authorities over the alleged firearm purchases and his activity online.
"We took all the guns and ammo out of his room and got it off our property," she told a 911 dispatcher, according to records obtained by Fox News Digital. "He just came inside, and he's probably going to discover it's not in his room."
