SAN DIEGO — A multi-vehicle crash involving an MTS bus is believed to have been caused by a driver who ran a red light, according to the San Diego Police Department.

The incident occurred shortly after 8:30 a.m. on Sunday. Police said a 29-year-old woman was driving her 2009 Nissan Versa southbound on 54th Street, approaching the intersection with College Grove Drive, when a 55-year-old female was traveling eastbound through the intersection in her 2012 Toyota Highlander.
