ANAHEIM, Calif. (AP) — A federal jury says an Anaheim police officer used excessive force in shooting an unarmed gang member in 2012 — a death that sparked angry protests.

The Orange County Register reports that jurors ruled Thursday in a lawsuit filed by the mother of 25-year-old Manuel Diaz.

He was shot in the back after running from the officer down an alley.

Officer Nick Bennallack testified that he fired after Diaz ignored commands to stop and appeared to be reaching for a gun in his waistband. Diaz didn't have a weapon.

The shooting of Diaz and another man on consecutive days led to four nights of looting and raucous street protests.

In a statement after the verdict, Anaheim spokesman Mike Lyster said the city believes the officer acted reasonably.
