Three people were injured during a drive-by shooting outside Temple University Hospital early Thursday morning, according to police.

An 18-year-old was shot in the hand, a 22-year-old was shot in the knee and a 25-year-old man was shot in the face, back and arm, police said. They each were able to walk into the hospital and are in stable condition, according to 6ABC.

At least 40 shots were fired at the men, with some bullets striking the side of the hospital, investigators said.

"It's very unusual for someone to fire 40 shots right outside of Temple Hospital, specifically Temple Hospital's emergency room," Philadelphia Police Chief Inspector Scott Small told NBC10.

At least three people are believed to have fired shots using semi-automatic guns from a dark-colored four-door sedan, investigators said. One of the shooters may have exited the vehicle to fire shots.

A dark-colored, four-door sedan was spotted traveling south on Germantown Avenue, Temple police said.

Just hours before the shooting, police had gathered outside the emergency room to await the release of an officer who had been shot in the hand, 6ABC reported.

Police are reviewing surveillance footage, but do not have a motive for the triple shooting. Witnesses on the scene did not believe any of the victims returned fire, according to NBC10.
