LIVERMORE -- A former campus supervisor at the Livermore Valley Charter School was arrested Friday on suspicion of abusing a 14-year-old student at the school in 2010 and 2011, police said Monday.
Jason Quero, 30, had worked at the school since 2005. While serving as a campus supervisor, Quero also contracted with the school to provide after-school karate lessons to students under the name Golden State Seibukan Academy.
Police said that Quero had sexually abused a 14-year-old female student at the school, but did not provide further details. Quero is no longer employed by the school.
Quero was held on suspicion of penetration with a foreign object of a victim under the age of 16 and of oral copulation with a victim under 16. Both charges specify that the suspect abuser is above the age of 21.
A statement from the Tri-Valley Learning Corporation, which operates the charter school, said that officials were cooperating fully with the police investigation and conducting a simultaneous personnel investigation.
Quero had previously worked as a substitute campus supervisor at Arroyo Mocho School in Livermore from 2003 to 2005. Before that, he was a teacher's aide for the Livermore Area Recreation and Parks District from 2001 to 2003, also working at Arroyo Mocho School.
Police are asking parents to talk to any children who may have had contact with Quero. Anyone with information about the case is asked to call Livermore police at 925-294-7531; tipsters can remain anonymous if they desire.
