A gunman who claimed to have pledged allegiance to Islamic State in Iraq and the Levant (ISIL) shot and seriously wounded a Philadelphia police officer while he sat in his patrol car in an ambush-style attack, the city's police commissioner said on Friday.
Gunman Edward Archer of Philadelphia, who has been arrested, fired about 11 shots through the window of the officer's car, Philadelphia Police Commissioner Richard Ross told reporters. He walked toward the car as he fired, eventually getting close enough to reach in the window.
"He has confessed to committing this cowardly act in the name of Islam," Ross told a press conference, adding that the man also referenced ISIL fighters.
Philadelphia Police Captain James Clark added, "He said he pledges his allegiance to Islamic State, he follows Allah and that was the reason he was called on to do this."
U.S. officials have been on high security alert following a series of ISIL-linked attacks at home and abroad over the last few months.
In November, gunman and suicide bombers affiliated with ISIL killed 130 people in a series of coordinated attacks in Paris. Last month a married couple fatally shot 14 people in San Bernardino, California, in an attack inspired by the armed group.
There was no evidence as yet that the shooter had worked with anyone else, Ross said.
"He was savvy enough to stop just short of implicating himself in a conspiracy," Ross said. "He doesn't appear to be a stupid individual, just an extremely violent one."
Officer Jesse Hartnett, 33, who pursued the shooter, was taken to Penn Presbyterian Hospital and will require several surgeries.
"We're just lucky, that's all I can say," Ross told reporters. "I can't even believe that he was able to survive this."
The shooter used a gun that had been stolen from a Philadelphia police officer's home several years ago, but not by the shooter, Ross said.
"We know it was stolen, how many hands it may have passed through in the last couple of years, we do not know," Ross said.
Police released still images from a surveillance video that shows the gunman, dressed in a white robe, walking toward the patrol car right up to the driver's side door. He was firing all that time, police said.
