The arrest came during a heightened effort from Oakland police to bring the recent surge violence in Chinatown to an end.

In a two-week span in February, authorities recorded 18 crimes against Asian Americans around Oakland’s Chinatown, according Alameda County District Attorney Nancy O’Malley. She has launched a special unit within her department to investigate the attacks.

To counter the surge in violence, recently named Oakland Police Chief LeRonne Armstrong has deployed the department’s mobile community command unit to Chinatown and increased police street patrols. He also took the streets to personally assure residents and business owners that his department was there to protect them.

“We wanted our business owners and community to know that we care,” Armstrong said. “That we are concerned and are going to do everything to keep the community safe.”
