A shooting suspect who sparked an hours-long search at a North Long Beach apartment building on Monday ended up turning himself in at a police station later that night, according to authorities.

Police say they arrested 24-year-old Michael Brown Jr. on suspicion of attempted murder after he surrendered around 10:30 p.m.

His arrest was at the end of a chaotic day for residents at the apartment complex on Paramount Boulevard near South Street. It started when a gunman approached a man at around 10:30 a.m., shot him and fled, according to police.

The suspect and victim knew each other and the victim was left in critical but stable condition. It’s unclear what prompted the violence.

Detectives quickly homed in on Brown as a suspect. They believed he was hiding in his apartment on the 2600 block of 56th Way shortly after the shooting.

Officers set up a perimeter around the complex for hours, calling out Brown’s name over a loudspeaker. By about 5 p.m., however, police determined he was not inside and broke down the police tape.

Police detained two people for questioning on Paramount Boulevard around 4:30 p.m., but said neither were the suspect.

Hours later, Brown surrendered, and he’s now being held in jail on a $1 million bail, authorities said.
