A retired Los Angeles Police Department commander has been named the new chief of police in Riverside. Sergio Diaz is scheduled to begin his new job on July 1.

Diaz replaces former chief Russ Leach who was granted a medical retirement after pleading guilty to misdemeanor driving under the influence.

A California Highway Patrol investigation found that Leach was pulled over Feb. 8 by officers after leaving a topless bar in Colton, where he had seven of his 11 drinks on Super Bowl Sunday. Authorities say he was driving a damaged city-issued car with no headlights and smelled of alcohol.

Diaz retired from the LAPD in April.
