An investigation into an 18-year-old in Ohio has resulted in his arrest on charges of threatening to assault a federal law enforcement officer.
According to Fox News, the investigation started in February when FBI agents found online comments from the boy supporting mass shootings and attacks on Planned Parenthood.
Though investigations started six months ago into the boy’s activities, prosecutors say it was necessary to act now because of recent mass shootings across the U.S.
Olsen, who lives with his father, was arrested last week. He was charged Monday with threatening a federal officer.
According to court documents, Olsen told the FBI during his arrest that the comments were only a joke.
But the agents reportedly found 15 rifles, 10 semi-automatic pistols, camouflage clothing, camouflaged backpacks, and roughly 10,000 rounds of ammunition in his bedroom during the arrest.
