Pleasanton police investigators announced last week that an Oakland teen has been arrested in connection with an incident from December in which a woman was attacked and robbed in her driveway on Chardonnay Drive.
The boy was taken into custody Feb. 16 on suspicion of robbery and elder abuse, according to a post on the police department's Facebook page. Two other teens suspected of being involved in the crime remain at-large.
The robbery took place on the evening of Dec. 7 when a woman returned to her home on Chardonnay Drive -- located near the intersection of Vineyard and Bernal avenues -- after shopping at Target in Livermore. Two black males approached her in her driveway and assaulted her while a third black male stole her purse, according to police.
The assailants then fled the area after being scared off by a neighbor, police said.
The department's criminal investigations unit soon took over the case and decided to re-interview two teen girls who were found in the neighborhood the night of the robbery, according to police.
During the new interviews, the girls admitted to being with the three teen boys the night of the robbery, although denied knowing the suspects' names and said they only communicated with the boys via Instagram, police said.
The girls also allegedly admitted the suspects followed the victim from Target to her residence on Chardonnay Drive.
Investigators then received search warrants for several Instagram accounts and identified one of their suspects as a 17-year-old boy from Oakland. He was arrested around 6 a.m. Feb. 16 when police served search and arrest warrants at his home in Oakland, police said.
The investigation is still ongoing, and officers are working to identify and find the two other assailants, police said. Anyone with information about the case can call the department at 931-5100. Reference case No. 17-50063.
