The group then got onto a private party bus that drove north on Pacific Coast Highway. Officers stopped the bus a short distance away, Marlatt said.
There were about 80 people on the bus, requiring Huntington Beach police to request assistance from Newport Beach, Costa Mesa, Seal Beach and Laguna Beach police departments, she said.
Seven loaded handguns were recovered on the bus. During the investigation, officers arrested Isiah Bryant, 21 of Los Angeles and Wynzel Worthan, 18, of Compton for robbery and conspiracy. They were booked into Huntington Beach Jail.
