26-year-old Anel Cuenas was arrested around 4:45 a.m. Monday.
Officials say Cuenas shot Officer Kevin Livewell in the leg during a shootout after a traffic stop on Thursday night.
SWAT and U.S. Marshal's stormed a row home on the 3300 block of Potter Street. Investigators say Cuenas was hiding out with relatives. He tried to flee, police said, but was quickly apprehended.
Police say Livewell and another officer stopped a van believed to have been involved in an earlier shooting. As the officers approached the van, shots rang out.
One man was later captured, and police say he was the van's driver. He has been identified as 36-year-old Ramon DeJesus. He is being held on two counts of attempted murder of a police officer.
Police say another man was in the van, and remains at large. There is no word yet on his identity.
"We are following leads as we speak, we have not clearly identified that third person," said Deputy Commissioner William Blackburn, but added investigators are pursuing several leads.
Over the weekend, a man was questioned by police, but he was released without being charged.
Following the shooting, police said they recovered a large number of automatic weapons, including an AK-47 that, they say, was used to shoot Officer Livewell.
"I have almost 30 years of police experience, and I've never seen that type of weaponry, that type of high-powered weaponry in an episode like this," said Blackburn.
Officer Livewell is married with two children and is a 9 year veteran of the Philadelphia Police Department.
Officer Livewell underwent another round of surgery on Monday and should be released in a few days.
