Delta police are investigating after a teen was assaulted on a bus over the weekend.

At around 9: 45 p.m. Sunday, two 14-year-old boys were traveling on a bus from 12th Avenue and 56th Street in Tsawwassen when an older teen approached one of the boys, challenged him and then punched him in the face.

The suspect is described as a Caucasian male, about 18 years old wearing a red baseball hat and jeans. He exited the bus at the next stop.

The injured boy was later taken to the hospital. He ended up with a chipped tooth. The incident is still under investigation.
