Livermore police have arrested a man who allegedly assaulted and tried to rob two women May 21 at the Arroyo Shopping Center, despite wearing an ankle-monitoring device from a previous conviction.

Around 5 p.m. May 21, police responded to numerous reports of an altercation in the parking lot of the Arroyo Shopping Center, in the 4300 block of First Street.

Colby Berry, 21, allegedly assaulted a woman with a weapon and attempted to grab her purse. The woman fought back after Berry allegedly "violently attacked her for more than 30 seconds," police said, on social media.

Berry then allegedly attacked a second woman and stole her purse at gunpoint. Both victims were in their 20s, one from Livermore and one from Discovery Bay.

Berry allegedly then drove away. Investigators discovered it was Berry, a Fremont resident on parole for a shooting at an inhabited dwelling in 2021 and who is currently wearing an ankle monitor.

The ankle monitor determined Berry was at the scene of the Livermore robberies, police said. With help from Berry's parole officer, Livermore police arrested Berry Wednesday at the parole office in Oakland.

A search warrant for Berry's home turned up a Glock handgun believed to have been used in the robberies. Police took Berry to Santa Rita Jail, where he faces several charges, including two counts of felon in possession of a firearm, carrying a concealed weapon, attempted robbery, robbery, and assault with a deadly weapon.
