VERO BEACH — A Vero Beach High School student was arrested on felony charges after deputies received an anonymous tip he had brandished a gun on campus Friday afternoon.

Andrew Bobilin, 17, of the 1300 block of 25th Avenue Southwest, was charged with possession of a weapon on school property and carrying a concealed firearm.

An anonymous caller left a message about Bobilin on the Sheriff's Office tip line about 6 p.m. Friday.

The caller told deputies Bobilin had a gun in the high school's junior parking lot shortly after 2 p.m.

Bobilin was heard saying, "$100 bucks and I'll shoot a cap," according to his arrest affidavit. He then pulled a small black semi-automatic pistol out of his boot and pulled back the slide, as if he were readying it for fire, the affidavit said.

Deputies arrested Bobilin on Sunday after reviewing campus video surveillance. He was taken to the Department of Youth Services, sheriff's officials said.

A .380-caliber handgun was recovered, which witnesses identified as the weapon Bobilin had on campus.

"'See something, say something' works. It is not just a slogan," Sheriff Deryl Loar said Monday in a news release.

"We want to assure the parents, teachers and students of Indian River County that if you come forward with a tip, we will thoroughly investigate the allegations."
