The gunman suspected of shooting a Philadelphia cop through the window of his squad car admitted to the attempted “execution” and claimed he did it in the name of Islam, according to local media.

Police have not released an official motive in the Thursday night attack and have not said if they are investigating it as terrorism.

Officer Jesse Hartnett suffered a broken arm and nerve damage during the harrowing ambush, but was able to fire back at his assailant. The attack was caught on surveillance video, which showed the shooter fire more than a dozen times as he advanced toward the cop’s car until he was next to the driver’s side window.
