Nearly a dozen Apex police officers, including the police chief entered a teen's home last week and seized ammunition and what they described as an "AK-47-style" firearm.

The police seized the firearm and ammunition from 100 Walnut Hill Court last week, after reports that 17-year-old Ryan Patrick Hare had threatened to blow up a school bus, according to a search warrant made public last week at the Wake County Clerk of Courts Office. Hare was reprimanded last month for shooting at a school bus with a paint-ball gun.

Cary police charged Hare, a student at Panther Creek High School, with possession of paint-ball guns while on school property, according to the warrant.

Apex Police Chief Jack Lewis said the firearm confiscated in the search had been legally bought by the student's father. No arrests have been made in connection with the threat.

Apex police searched the home of Hare's parents after learning from the Cary Police Department that the youngster was overheard at school saying he was going to put a C-4 explosive under a bus and blow it up, according to the search warrant.

Ten officers announced their presence before walking throug the unlocked door of the home March 4, Lewis said. He described the police investigation of the threat as ongoing.

"Our concern has everything to do with receiving credible information about threats being made," Lewis said Wednesday.
