A masked gunman who fired 13 shots at a Philadelphia police officer as he sat in his marked cruiser at an intersection has pledged allegiance to ISIS.

The suspect, named by police as Edward Archer, opened fire at Officer Jesse Hartnett as he sat alone in his car late on Thursday.

Hartnett, who was wearing a bullet vest, was hit three times in his left arm, but miraculously got out of the car to continue to shooting as the gunman ran away.

At a press conference this afternoon it was revealed Archer, who has a criminal record, used a police handgun reported stolen in 2013.

The 30-year-old, who was also hit three times, was taken into custody shortly after the 11:30 p.m. ambush.

Police Commissioner Richard Ross said Archer pledged allegiance ISIS and told investigators that he believed police defend laws that are contrary to Islam.

He said there was no indication from Edward Archer, of Yeadon, that he was involved in a conspiracy.

Mayor Kenney stressed whatever the gunman's motive, it had 'nothing to do' with Islam.

Hartnett is in a stable condition and underwent surgery early Friday at Presbyterian Hospital.

Images from the horrific attack were shown at the press conference.

Ross said: 'This is absolutely one of the scariest things I've ever seen.'

'This guy tried to execute the police officer. The police officer had no idea he was coming.'

He said Hartnett was in his cruiser in West Philadelphia when the shooter approached from the sidewalk.

He then began firing, eventually shooting through the driver's-side window as he got closer.

'I'm bleeding heavily!' Hartnett, a veteran of five years on the force, shouted into his police radio when he called in to report shots fired.

The suspect, who used a 9mm handgun, ran away but was quickly apprehended by other officers.

Ross said the gunman used a gun that was stolen from the home of a police officer in 2013.

'That is one of the things that you absolutely regret the most,' he said.

'When officer's gun is stolen and it's used against one of your own.'

Archer's mother, Valerie Holliday, told The Philadelphia Inquirer he has been hearing voices recently and that family asked him to get help.

She told Philly.com, that he was one of seven children and that he had suffered head injuries from playing football and a moped accident.

'He's been acting kind of strange lately. He's been talking to himself . . . laughing and mumbling,' Holliday said. 'He's been hearing voices in his head. We asked him to get medical help.'

She added that Archer believed he was targeted by police.

The officer's father, Robert Hartnett, said he spoke to his son after his surgery.

'I love him and very proud of him. He's an excellent person,' Robert Hartnett said, reports 6ABC.

'His spirits are positive,' Richard said, saying his spirits are positive, 'now that I see he's waking up. It will be a tough road. But he's a tough guy.'

Hartnett grew up in East Lansdowne with three siblings. He went from the Coast Guard to the police academy, according to 6ABC.

'Jesse you're a super hero,' his sister-in-law Ashley Hartnett wrote on Facebook today.

'My brother in law, a police officer in West Philadelphia, was shot at 13 times point blank while sitting in his patrol car at a red light last night … But it's harder than that to take down a Hartnett.'

Police said they will not be releasing video of the attack out of respect for the officer and his family.

Jim Kenney, in his first week as mayor of the nation's fifth-largest city, said, 'There are just too many guns on the streets, and I think our national government needs to do something about that.'

His statement comes on the heels of President Barack Obama's announcement Tuesday of his plan to tighten gun control laws.
