A student at Jeremiah E. Burke High School in Dorchester allegedly brought an unloaded revolver into the school and bit a Boston police officer on the wrist as officers tried to wrestle him to the ground and remove the gun from his backpack, said Suffolk District Attorney Daniel F. Conley’s office.
The 17-year-old student was arraigned Friday in the juvenile session of Dorchester Municipal Court, where he faced charges of unlawful possession of a firearm, assault and battery on a police officer, and resisting arrest, prosecutors said. The teenager pleaded not guilty to all charges.
Bail was set at $10,000 cash, and he was ordered to stay away from the school, prosecutors said. His name was not released because he is being prosecuted as a juvenile.
According to prosecutors, the teenager bragged to classmates that he had sneaked a gun into school in his backpack.
About 2 p.m. Thursday, police located the student in a classroom.
As they approached him, he “became tense and combative’’ and reached into the backpack, prosecutors said.
“During a violent struggle with police, the teen bit one officer on the left wrist,’’ prosecutors said. The teenager also suffered a head cut during the struggle and was treated at the scene.
Authorities said the gun had been painted black, pink and white, which obscured the make, model and serial number of the weapon.
