Investigators of the Western Police District Homicide Section identified the victim as Sonny Balboa, 35, of Pier 2, Tondo.
Police said the victim was asleep inside the shanty of his girl friend inside Pier 4 when the suspect identified as a certain "Popong" and two others shot him at about 11:30 p.m.
Police said Balboa died on the spot from three gunshot wounds in the chest.
Police investigation showed that "Popong" allegedly wanted to get back at Balboa after the victim had allegedly tipped off police about his alleged drug pushing activities a week ago.
Police said operatives of the Western Police District Drug Enforcement Group later arrested "Popong" but released him for lack of evidence.
Relatives of the victim later told police that the suspect allegedly threatened to get even with Balboa and a certain Antonio Reyes for reporting his alleged activities to the police.
