The Massachusetts Bay Police Department has called for criminal charges after an MBTA bus crashed into two homes and several parked cars in Medford early in the morning. The driver, a 40-year-old man, crossed over double yellow lines and failed to stop for a red light at the I-93 off ramp on the Somerville-Medford line, according to Transit Police. The bus driver has since been suspended. Police are seeking several criminal violations including Negligent Operation of a Motor Vehicle and Failure to Stop at a Red Light.
