Mobile police on Friday arrested five teenagers at Davidson High School on gun, drugs and other charges stemming from an investigation into youths who unlawfully entered a home.

Officers following up on the investigation around noon Friday found a 17-year-old boy with a gun in his backpack at the high school, Cpl. Katrina Frazier said Monday.

A 16-year-old girl was in possession of marijuana, police said, while two 16-year-old boys and a 15-year-old girl were charged with third-degree criminal mischief and first-degree trespassing, Frazier said.

All five teens, who allegedly unlawfully entered a home in the 4000 block of Yorkshire Lane, were taken to Strickland Youth Center.
