PHILADELPHIA, USA - A man who barricaded himself inside a Philadelphia house and opened fire at officers, injuring six, has been taken into custody after a standoff with police that lasted more than five hours.

Philadelphia police spokesman Sergeant Eric Gripp has confirmed that the gunman was apprehended, adding that SWAT teams have been clearing the premises.

The suspect gave himself up to police around midnight, exiting the house with his hands in the air, WTXF-TV reported, citing an officer at the scene.

Multiple media outlets, citing police sources, have identified the gunman as Maurice Hill, 34, a Philadelphia native whose extensive criminal record goes back to the early 2000s.

The incident began unfolding at 4:30 pm local time in the Nicetown-Tioga section of the city, after police tried to serve a drug warrant.

A bullet grazed an officer's head in the ensuing gun battle. Two other officers suffered arm injuries. They were all released from the hospital later that evening. Another officer was injured in a traffic accident while driving to the scene.

A SWAT team was able to rescue two police officers and three civilians trapped inside the house.

Earlier, another suspect believed to be Hill’s accomplice surrendered to police.

The shootout was closely followed on social media, with Hill reportedly livestreaming the crime on Facebook.

Hill has been described as a hardened criminal who served multiple stints in prison for an array of serious offenses, ranging from illegal possession of weapons to aggravated assault. He was barred from purchasing firearms due to his  criminal record.
