A man was recovering Thursday from three stab wounds inflicted during a group fight in Hollywood, police told Patch.
The melee among a "handful" of people occurred shortly after midnight Thursday on Hollywood Boulevard near Bronson Avenue, LAPD Lt. Marc Reina said.
Police in the area spotted a group fight, the lieutenant said, but when they approached the group, the scrap was just ending.
Police walked up to one man, who then realized he had been stabbed; he pointed out a suspect, Reina said.
The suspect ran off but was chased and quickly caught, Reina told Patch.
The 19-year-old suspect, was taken to a station for questioning and the 18-year-old victim was taken to a hospital, where he was expected to recover, police said.
Reina told Patch that the weapon used appeared to be a makeshift knife.
A motive for the stabbing was under investigation.
