PHILADELPHIA (AP) — Gunfire killed three people and wounded at least 11 others in a popular downtown Philadelphia entertainment district late Saturday night, authorities said.

Police officers were patrolling the area on South Street in downtown Philadelphia when they heard multiple gunshots and witnessed several suspects firing into a large crowd just before midnight, Police Inspector D. F. Pace said during a news conference.

An officer shot at one of the suspects from about 30 feet (9 meters) away, but it is unclear if the suspect was hit, Pace said.

“You can imagine there were hundreds of individuals just enjoying South Street, as they do every single weekend, when this shooting broke out,” Pace said.

Two men and a woman were among those killed in the shooting, he said. Their names were not made public by authorities. The conditions of those who were wounded by gunfire remains unknown.

Two handguns were recovered, including one with an extended magazine, police said. No arrests have been made.

South Street is known for its entertainment venues and night life with multiple bars, restaurants and businesses. Surveillance video from a local business posted by WTXF-TV showed scores of people milling about on the sidewalks and in the street who then suddenly began to flee in masse as the gunfire began.

Pace said police expect to be able to gather “a lot of video surveillance footage” from the many businesses along the street later in the day to try to identify suspects.

Eric Walsh, closing up the outdoor seating area of a bar along the block, told The Philadelphia Inquirer that the scene was “chaos.” He said he saw a young woman collapse to the ground on the corner.

“People were coming off the street with blood splatters on white sneakers and skinned knees and skinned elbows,” Walsh said. “We literally just were balling up napkins and wetting them and handing them to people.”
