PHILADELPHIA – Police shot and killed a man on a Philadelphia street Monday afternoon after yelling at him to drop his knife.

The shooting occurred shortly before 4 p.m. as officers responded to a report of domestic violence.

Sgt. Eric Gripp, a police spokesman, told The Philadelphia Inquirer that officers were called to the Cobbs Creek neighborhood and encountered the man, who was with at least one other person, and “they appeared to be in some sort of altercation.”

Gripp said officers ordered the man to drop the knife, but he instead “advanced towards” them. Both officers then fired “several times,” Gripp said. One of the officers put the man in a police vehicle and drove him to a hospital, where he was pronounced dead a short time later.

Video of the fatal confrontation recorded by a bystander and posted on social media shows officers pointing their guns at a man as he walked in the street and around a car. The man walks toward the officers as they backed away from him in the street, guns still aimed at him. They yell at him to put his knife down.

Also in the video, the woman identified as his mother pleaded with the officer not to open fire while also trying desperately to stop him moments before the officers opened fire and killed him.

Both then fired several shots at the man and he collapsed in the street. A woman ran up to the victim and began screaming. Several bystanders then walk up to the man who was shot.

It is unclear in the video if the man had a knife. Witnesses said he was holding one.

No officers in the video appeared to be injured. The names of the officers who fired the shots were not immediately disclosed. Both were wearing body cameras and were taken off street duty pending the investigation.

A large crowd gathered where the man was killed, with a video showing many yelling at the police officers and crying. Some people later spoke with city Police Commissioner Danielle Outlaw, who arrived at the scene a short time after the shooting occurred. The crowd had mostly dispersed about two hours later.

A police spokesperson did not immediately respond to an email seeking information about the shooting.
