An officer responded to the Ashby Station regarding a child (6-7 years old) that had been abandoned at the station by his mother. The officer contacted a relative who stated the mother has alcohol dependency problems and often leaves the child alone. The friend added a friend of the mother’s had temporary custody of the child and would return him to the station. The child was returned to the station and the officer contacted Child Protective. CPS took custody of the child and he was dropped off at the assessment center. The mother showed up at the station, approximately one hour after the call and had been drinking. She was placed under arrest by the officer for child endangerment and was booked at Santa Rita Jail. A sergeant approved the arrest.
