"As members of the ERT were approaching the door, they were met with gunfire," Morris said. "One of our officers was struck. There was an exchange of gunfire at that point in time. The returned fire struck him [the gunman] as well."
Then the gunman barricaded himself inside for three hours before police stormed the house and took him into custody, the chief said. Both the detective and the gunman were hospitalized, he said.
The five-unit apartment house where the gunman was arrested is a block south of East Tilghman Street and little more than two blocks from East Tilghman and Hart streets, where the unidentified woman's body was found 2:45 p.m. Sunday.
The detective, an officer in his 30s, was taken to Lehigh Valley Hospital-Cedar Crest with a wound to his left arm, according to emergency radio reports. Morris said he was in stable condition and was later released.
