A 14-year-old was arrested for allegedly burglarizing at the Promenade mall.
The store's alarm sounded at 4:40 a.m. Monday, according to sheriff's Sgt. J. Larson.
"Officers formed a perimeter around the building," Larson wrote in an announcement. "The suspect exited the store through the front door. Officers detained (him) and determined that he was a 14-year-old juvenile."
Officers found two 4S iPhones on the teen, who was taken into custody and brought to the , the sergeant said.
Law enforcers searched the store and found nobody inside. "There are no other known suspects related to this incident," Larson wrote.
The officers reviewed security footage and found the boy slipped in through the front door as though it were unlocked, and no evidence of forced entry was found, sheriff's Sgt. Michael Driever told the Press-Enterprise.
The footage also shows the last employee to leave for the day locking the door and tugging on it to make sure it was secure, the newspaper reported.
This is at least the second time the store was invaded within the last 13 months.
In January, 2011, two men slipped into the store after hours and held up the employees. In this case, the door was supposed to be locked, but the suspects opened it with ease.
