The BART Police Department has taken a man into custody in connection with a reported sexual assault Friday in a Millbrae Station parking garage elevator.

Authorities say a woman told police she had been assaulted by a man after a BART station agent observed her in the station on closed-circuit television prior to morning train service commencing. The reported assault took place during the overnight hours when BART trains were not in service.

BART police identified the suspect as 38-year-old Roberto Marenco. At 8:45 p.m., BART police, along with the Clayton and Concord Police departments, took Marenco into custody. Police gave no further details.
