An attack by a knife-wielding woman on an officer from a Delaware County police department was caught on a cell phone video camera.
It all started last Sunday when a Chester City police officer responded to a 911 call about a woman waving a knife at people at a gas station along 9th Street.
"She was wielding a knife and yelling and screaming at people walking past her," said the witness who caught the entire incident on camera.
The video shows the officer approach the woman and the woman throwing the knife at him.
The witness, who asked to remain anonymous, says that although the woman did attempt to hit the officer with the knife, his reaction was unnecessary. He can be seen on the video hitting her several times before Tasing her.
"...Just because he's an officer of the law and he wears a badge, doesn't take away he used excessive force on this female."
Chester Police Commissioner Joseph Bail told NBC10's Neferti Jaquez that although the video doesn't look good for the officer, the public should wait to jump to conclusions.
"We will have it investigated," said Bail. "Anytime we have officers involved in questionable activity, it's bothersome to us."
The officer, who was injured in the attack is off the streets. An investigation is underway.
The woman in the attack is facing multiple assault charges.
