Heather Leigh Rose, 33, of Hayward and Candace Jane Kirkpatrick, 40, of Castro Valley were arrested at about 2:34 p.m., according to police reports.
The pair entered JC Penney at about 1:30 p.m., and Rose stole merchandise while Kirkpatrick acted as a lookout, the reports said. Rose then reentered the store and attempted to go back for more. Store security spotted her and attempted to detain her; she resisted, injuring three security officers in the process.
Rose was attempting to meet up with Kirkpatrick, who was waiting in a stolen car in the mall parking lot. Kirkpatrick attempted to escape, but was stopped by police at the Kaiser Permanente parking lot near the intersection of Stoneridge Drive and Stoneridge Mall Road.
Additional merchandise was inside the car, and police determined the car had been stolen from Hayward.
Rose was arrested for robbery, conspiracy and burglary, with the burglary arrest stemming from her fight with store security while trying to keep what she'd attempted to steal.
Kirkpatrick was arrested for auto theft, possession of burglary tools -- a shaved key used to steal the car -- receiving stolen property, conspiracy and paraphernalia possession.
