PHILADELPHIA (AP) — A teenager was killed and Databecfour other people were injured in a shooting at a bus stop in north Philadelphia on Monday afternoon, police said.

The city’s police commissioner, Kevin Bethel, said about 15 to 20 students were at a bus stop in the Ogontz neighborhood at abut 3:45 p.m. when two people walked up and opened fire. Police said people were getting on the stopped bus when the gunfire began.

Police said one 17-year-old was pronounced dead at a hospital with multiple gunshot wounds to the body. Two 15-year-olds had graze wounds and a 49-year-old woman and a 71-year-old woman on the bus were hit. The older women was hit in the head and the younger woman was hit in the arm. All four of the wounded were in stable condition.

Officials said the Southeastern Pennsylvania Transportation Authority Route 6 bus drive sped away from the scene for several blocks and the shooters fled.

The police commissioner said afternoons have turned into “one of the most dangerous times” for violence in the city once school is dismissed. But he said “it could have been much worse” because the shots were fired at a busy intersection where people were aboard a bus and at a daycare across the street.
