Police say the suspect in the shooting of a Philadelphia police officer told investigators that he shot the officer in the name of Islam and pledged allegiance to the Islamic State group.
They also say the man, who has addresses in Philadelphia and the suburb of Yeadon, used a stolen police gun in the crime.
Police officials say the gun was reported stolen from an officer's home in October 2013 but they don't know how many hands it passed through before being used in the Friday morning shooting.
The officer has been identified as Officer Jessie Hartnett. He was shot three times in the arm. The officer fired back and wounded the suspect.
