Former Woburn High School football player Johnathan Coucelos said he was assaulted and bullied by teammates in the locker room, and the school did nothing to protect him. Now, police are filing criminal charges against seven students accused of the assault.

Coucelos, who is 14, told Jim Braude on Greater Boston Monday that his life has changed drastically since the attack, and the harassment has not stopped. "I lost half of my friends. It doesn't feel the same anymore to be out in public," he said.

He added, "I used to wake up and go out with half of my friends and now I'm just locked up in my room and finally going into a different school."

The teen was joined by his parents Kevin and Jeanny and his lawyer Peter Hahn, who said the school failed Coucelos. "They haven't given my son or even us any support whatsoever," Kevin Coucelos said. "It's just so wrong how they're handling it. It gets me emotional every time I have to talk about this."

The family is asking for accountability from the school. Coucelos reported the violent incidents to coaches and the police who did not take enough action.

Jessica Callanan, principal of Woburn Memorial High School said in a statement to Greater Boston, "the Coucelos family’s complaint is and should be taken seriously. Multiple investigations are being undertaken. I urge all people involved to cooperate completely with the investigators so that the best and most just outcome can be reached. Today and every day, I urge every member of our community to be kind to one another and do everything in their power to be part of making our community kinder and stronger."
