Pleasanton police confirmed a third teenager was arrested early Wednesday in connection with two robberies at Stoneridge Shopping Center last weekend.
Pleasanton police said they were in the process of interviewing the 17-year-old boy to confirm whether he was involved with two purse-snatchings at the mall.
Two other 17-year-old boys were arrested Monday in connection with the thefts after a 63-year-old woman and a 17-year-old Danville girl were robbed of their purses by three teenagers in separate incidents last weekend.
Last Sunday afternoon, a 63-year-old woman who was standing by her car at Stoneridge Shopping Center was kicked, threatened with a gun and robbed of her purse Sunday afternoon, according to Pleasanton police.
The woman was standing by her car when three teens came up to her. One grabbed her purse, and the woman pulled back on it as another teen pulled out a rifle or shotgun, according to police.
On Saturday night, a 17-year-old girl from Danville was walking to her car in the mall parking lot when three men left a silver SUV and one grabbed her purse, according to police.
When she resisted, one teen allegedly punched her in the face and pushed her to the ground. The teen reportedly did not require medical attention.
The silver SUV was later reported in a car-jacking incident at the San Leandro BART station, where three African-American teens drove up in the vehicle and stole a cream-colored Mercedes SUV, Schlehuber said.
The trip then took the Mercedes to Stoneridge Mall on Sunday and approached the 63-year-old woman. In that incident, the woman fell to the ground after struggling over the purse, and one of the men kicked her in the back before the trio ran away with her purse, according to police.
The woman reportedly sustained minor injuries but didn't need hospitalization. The boys left the mall in the Mercedes SUV, which drove onto westbound Interstate 580, police said.
Oakland police later found the described vehicle with two of the teens inside, and they were arrested and interviewed Monday. The third teen was detained early Wednesday morning.
