PHILADELPHIA (AP) - Authorities say an off-duty police officer shot and critically wounded a man he said lunged at him with a pair of scissors in south Philadelphia.

Staff Inspector Sekou Kinebrew said the officer was visiting friends at about 5:45 p.m. Saturday and heard a commotion and breaking glass outside. Kinebrew said he found the man, who is about 60 years old, dumping contents from a recycling bin and breaking glass items.

Police said the man then flashed pair of scissors at the officer and swung at him several times. Police said the officer then fired his own 9mm firearm at least four times, striking the man three times in the wrist, chest and leg.

The man was taken to Thomas Jefferson University Hospital in critical condition. Neighbors said the man is homeless and well-known in the neighborhood. His name hasn’t been released.

The officer, who has been on the force for three years, was uninjured. The police internal affairs bureau will investigate the shooting.
