Five people have been arrested in connection with the New Year's Day shooting death of a security guard at a Southern California roller rink.

Investigators say 48-year-old Richard Williamson died confronting a gunman firing at a crowd outside the Cal Skate rink in the city of Grand Terrace. Two other people were treated for injuries.

The San Bernardino County Sheriff's Department said Tuesday that all five face charges including murder and attempted murder, along with gang enhancements.

No ages were released but officials say three of the defendants are in custody at a juvenile facility.

Arraignment has been scheduled for Tuesday afternoon.
