A Fresno, CA teen’s post featuring Eminem’s lyrics led to his arrest, according to reports. After the 15-year-old posted lyrics from Em’s song “I’m Back,” police were prompted to conduct a search on his home. Guns and ammunition were found, which resulted in the teen’s arrest.

He was arrested for making terroristic threats, which is a felony, and disrupting school activity. His school, San Joaquin Memorial High School, was closed the day of the search.

On the song, the Shady Records rep raps “I take seven kids from Columbine, stand ’em all in a line / Add an AK-47, a revolver, a nine / A MAC-11 and it oughtta solve the problem of mine / And that’s a whole school of bullies shot up all at one time / I’m just like Shady and just as crazy as the world was over this whole Y2K thing.”

It was not only the lyrics but the additional content that the teen added that tipped the police off.

“I want to read that posting to you because part of the posting that was placed on Instagram is part of a rap song called ‘Rap God’ by Eminem, but you’ll see that this 15-year-old student added to that post some of his own words which is what caused the concern,” Fresno Police Chief Jerry Dyer said during a press conference.

Dyer mistakenly said the lyrics were from “Rap God” due to the song sharing the same line as “I’m Back”: “I take seven kids from Columbine, stand ’em all in a line / Add an AK-47, a revolver, a nine.”

After finding a replica AK-47 Airsoft rifle in plain sight, police returned with a search and found a .357 Magnum revolver, a 12-gauge shotgun, a handgun, ammunition and a bulletproof vest.

The teen’s father is also facing a negligent storage charge.

The teen claims that his computer was hacked and he did not make the post but he also allegedly told police that he deleted the Instagram post.
