An unknown male suspect allegedly made off with an undisclosed amount of cash from the Berkeley branch of the Patelco Credit Union in Downtown Monday morning.

At about 11:01 a.m., the Berkeley Public Safety Communications Center received a silent hold up alarm from the credit union — located at 2033 Shattuck Ave. — according to Berkeley police Sgt. Mary Kusmiss, spokesperson for the Berkeley Police Department. BPD officers responded to the scene and staged outside to wait for a response from the credit union about the situation inside.

During that process, the department got a call from an unknown person saying that the credit union was being robbed as more BPD officers arrived at the scene, according to Kusmiss. Employees at the credit union indicated to officers that the male suspect fled on foot just prior to their arrival and was last seen heading eastbound on Addison Street.

Kusmiss said in an email that the department notified neighboring agencies including the Bay Area Rapid Transit police.

As of 6:25 p.m. Monday, no arrests had been made and BPD officers and detectives were still investigating the case.

The suspect was described by witnesses as a black male adult, at about 6 feet or 6 feet and 2 inches tall, wearing a black and white baseball cap with a triangular logo and a black and white zip-up jacket with shaded lettering spelling “New York.”

Police are asking for anyone with information to call the BPD 24-hour non-emergency dispatch line at (510) 981-5900 and mention the robbery. Anonymous tips can be placed with Bay Area Crime Stoppers at (800)-222-TIPS.
