"Motorcyclists on Tear in Canyon"
Several cars from Malibu Sheriff's Station, manned by deputies, were rushed to Topanga Canyon shortly after 6 p.m. Sunday when calls for help were received from cafe owners threatened with depradations by a group of a dozen unidentified motorcyclists entering the canyon from the Coast Highway and escaping over the Topanga Summit into San Fernando Valley a few minutes before the officers arrived.
