Police were looking Monday for a gunman suspected of shooting another man at a North Hollywood apartment, where SWAT teams gathered in response to the incident.

Police received reports about 10 p.m. Sunday of a shooting between two men in the 12000 block of Oxnard Street. Witnesses told police the shooter had run into the nearby apartment house, said Los Angeles police spokeswoman Norma Eisenman.

The apartment walls were dotted with numerous bullet holes, and the second man was taken to a nearby hospital for injuries, she said, adding that he was not cooperating with authorities.

SWAT was called in and searched the apartment house for several hours before clearing the scene about 7 a.m. Monday, Eisenman said.
