Four students were stabbed after an argument on the Charm City Circulator bus downtown just before 4 p.m. Wednesday, police said.
The group was on the bus when a man estimated to be in his 20s boarded. The students "antagonized" the man, and an argument ensued that led to him pulling a knife on them, Baltimore police spokeswoman Sarah Connolly said. The bus driver quickly pulled over at the corner of Calvert and Redwood streets, where the group scattered.
The victims, whose ages were not available, had minor injuries from the fight and were treated at three local hospitals, Connolly said.
Police are still investigating.
