BRENTWOOD (BCN) — A suspect has been arrested in the fatal shooting that took place Thursday at a 24-Hour Fitness location in Brentwood. The suspect, a 17-year-old Brentwood resident, was one of two suspects identified early in the investigation.

He was positively identified as one of the shooters who was wounded in the incident, according to a release from the Brentwood Police Department. As a juvenile, he was booked into the Contra Costa County Juvenile Detention Center for murder.

A second suspect was released from custody after it was determined he was not the shooter.

Earlier on Friday, the victim in the shooting was identified by the Contra Costa County coroner’s office as 21-year-old Antioch resident Cesar Arana.

The shooting was reported around 1:55 a.m. Thursday at the 24 Hour Fitness gym on Lone Tree Way, where Brentwood police said a fight broke out on or around the gym’s basketball court and continued to its parking lot, where at least two people opened fire, based on surveillance footage.

Arana was pronounced dead at the scene, while the three others went to hospitals. Police said later Thursday that two people had been detained in connection with the shooting, but no arrests had been made. Anyone with information about the case is asked to call Detective Greene at (925) 809-7797.
