RALEIGH — An Athens Drive High School student was arrested after he was caught at school with a handgun Thursday.

A school resource officer with the Raleigh Police Department discovered the gun while investigating a theft, according to a letter that went out to parents from William Crockett, the school’s principal.

“While there was never a direct threat of harm to anyone, bringing a weapon to school is a very serious offense,” Crockett wrote.

Demetrius Brown,17, is charged with possession of a stolen firearm, having a gun on educational property, possession with intent to sell or deliver marijuana, carrying a concealed weapon and resisting a public officer.

Brown was found in possession of 3 grams of marijuana at the time if his arrest, according to his arrest warrant.

The handgun found by police was a .22 caliber Sig Sauer compact size pistol.

Neither the school nor police have released information about the theft that led to the discovery of the gun.
