Eight people were shot in a daytime attack on Wednesday near a Philadelphia bus and subway station, leaving one person in critical condition and seven others wounded, authorities said.

The shooting happened shortly before 3 p.m. ET (2000 GMT) near the Olney Transportation Center in the city’s Fern Rock neighborhood in northern Philadelphia, police said. The victims range in age from 17 years old to 71, police said.

One person is in custody, said Police Commissioner Danielle Outlaw in a brief press conference at the scene. But information on the suspect was not immediately available and no motive was known.

A 71-year-old man was shot in his stomach and both legs, police said. He is listed in critical condition at a nearby hospital.

Police initially said seven people were shot, but updated their information after they learned an eighth person walked from the scene to a nearby medical center with a “bullet graze wound to his stomach.”

The other victims also suffered wounds that ranged from being grazed by a bullet to suffering shots in the legs, arms, and ankle, Outlaw said. No other information was available on the wounded, other than they were in stable conditions, police said.

Two guns were recovered at the scene and at least 18 bullet shell casings littered the road, police said.

“We are still putting all the pieces together, but this was a very brazen incident,” she said.

Police are asking witnesses to the shooting to come forward and they are looking for other possible suspects.
