(Reuters) - A gunman opened fire from a moving vehicle outside a Philadelphia shopping center on Wednesday, wounding five young men, one of them critically, police said.

All five victims of the shooting, which was reported just after 2:30 p.m. EDT in the city’s Germantown section, were transported to nearby Einstein Medical Center, Philadelphia police said in a statement.

A 20-year-old man who was shot in the head was listed in critical condition at the hospital, police said. The other four victims, all men ranging in age from 19 to 23, were in stable condition with gunshot wounds to extremities.

No suspects were immediately taken into custody and no weapons were recovered at the scene, police said, asking for tips from the public in helping solve the drive-by shooting.
