DETROIT (AP) -- A man has been arrested following the stabbing of a 14-year-old boy on a Detroit public bus.
WDIV-TV reports that the teen identified his attacker from a police photo lineup.
Police say two riders were arguing on a Detroit Department of Transportation bus around 6 p.m. Wednesday. After the boy tried to intervene, a man involved in the dispute stabbed him in the chest.
Police tell the television station that the teen was defending himself and punched the man in the nose before the stabbing.
The boy ran from the bus and called 911. He was listed Thursday in critical condition at a Detroit hospital.
