A 15-year-old male was stabbed Thursday during a fight on a Metro bus in Southeast Washington, transit officials said.

The attack happened on a Route 92 bus as it arrived at the Congress Heights station about 4:40 p.m., said Caroline Lukas, a Metro spokeswoman. The teenager was stabbed in the upper back and on an arm, and was taken to a hospital with injuries that were not believed to be life threatening.

Officials think the 15-year-old had fought with another juvenile on the bus, but authorities were unsure of what prompted the fight.
