A 15-year-old student was arrested after he posted lyrics that referenced the Columbine High School massacre from Eminem's "I'm Back" on his Instagram page. Shortly after the post was discovered Monday night, authorities cancelled Tuesday's classes at Fresno, California's San Joaquin Memorial High School, where the student was a sophomore. The teenager was arrested and charged with making terrorist threats and police obtained a search warrant for the boy's home where they found a replica AK-47 Airsoft rifle, a handgun, a .357 Magnum revolver, a 12-gauge shotgun, ammunition and a bulletproof vest hidden in a closet, according to the Fresno Bee.

The boy's Instagram post featured the following lyrics: "I take seven kids from Columbine, stand 'em all in 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."

In a press conference held on Tuesday, Fresno police Chief Jerry Dyer said detectives, "have every reason to believe there was potential for a threat to be carried out" and described the student as a "loner" and "socially awkward. The teenager, however, contends that he did not make the Instagram post and that his computer may have been hacked. As far as the guns found in the house, the boy and his father both deny knowing about the unregistered weapons. Police took the teen into custody and made arrangements for a mental health evaluation.

"We have every reason to believe that he was reaching out for help," said Dyer. "The weapons were present. The ammunition was present. Perhaps even the mindset was present to carry out those threats.
