Police had a heavy presence outside the Twin Peaks restaurant before the melee broke out on Sunday, based on intelligence ahead of time about the five rival biker gangs meeting there, Swanton says. Gang members started shooting at one another, then turned their fire on police, Swanton says. Nine people died in the gunfire, he confirms. --SPA 03:32 LOCAL TIME 00:32 GMT www.spa.gov.sa/w
