A GUNMAN is in custody after opening fire on police as they were serving a drug warrant in Philadelphia.
Six officers were injured in an hours-long stand-off with the gunman, which began almost immediately when they went to a home in a north Philadelphia neighbourhood.
Philadelphia Police Commissioner Richard Ross said many of the officers "had to escape through windows and doors to get [away] from a barrage of bullets".
The six officers who were struck by gunfire were treated in hospital and later released.
Two other officers were trapped inside the house for about five hours after the shooting broke out but were freed by a Swat team.
Mr Ross said it was "nothing short of a miracle" that no officer was killed.
The suspect eventually surrendered several hours after the incident began when police used tear gas.
Amid the stand-off, dozens of officers on foot lined the streets, while others were in cars and some on horses.
The Bureau of Alcohol, Tobacco, Firearms and Explosives said its agents responded to the scene to assist police.
Philadelphia mayor Jim Kenney said he was thankful the officers' injuries were not life-threatening.
"I'm a little angry about someone having all that weaponry and all that firepower, but we'll get to that another day," he added.
