Police shot and critically wounded a man who, authorities said, advanced toward officers with a knife on a West Philadelphia street Wednesday evening and repeatedly ignored warnings to drop the weapon.

Officers responded to the 4900 block of Hazel Avenue about 7 p.m. for a report of a stabbing, said Capt. Sekou Kinebrew, a police spokesman.

“A male emerged from the property on the north side of the block carrying a knife, and he begin advancing toward the officers,” Kinebrew told reporters at the scene. “Both officers initially retreated, while giving him warnings to drop the knife. The male did not comply and continued advancing towards the officers.”

Neighborhood resident Robbie Woodruff told CBS3 he heard four gunshots.

The man, whose name was not immediately released, was shot once in the chest, police said. He was transported by police to Penn Presbyterian Medical Center, where he was reported to be in critical condition.

Police said they recovered a knife at the scene. They did not find anyone who had been stabbed.
