NAPA (KRON) — Police on Thursday announced a fourth suspect has been arrested in an alleged gang-related shooting in Napa last month.

Investigators say 19-year-old Leonardo Saldivar was arrested Wednesday in the 500 block of Even Street.

The arrest stems from a shooting in the 1000 block of Pine Street on May 30th, when one of several suspects in two vehicles fired shots at a rival gang member during a confrontation involving Norteno and Sureno gang members, Napa police Lt. Debbie Peecook said.

No one was injured, but the bullets struck two parked cars, Peecook said. Investigators say the shooting was in retaliation for a prior gang incident.

Earlier this month, police arrested Jose Manual Alcala, 23, and Valentin Michael Sanchez, 18, both of Napa. On Tuesday, they arrested 18-year-old Juan Carlos Solis, according to investigators.

Lt. Peecook said investigators will pursue attempted murder, assault with a deadly weapon, and gang participation charges against the suspects.
