WEST HOLLYWOOD—There were four arrests made at the annual Halloween Carnaval in West Hollywood on Monday, October 31. This is the second consecutive year that crime has been low in the region on Halloween night. In 2015, 3 arrests were made during the event.

The Los Angeles County Sheriff’s Department told Los Angeles Daily News that four individuals were arrested due to drunken and disorderly conduct.

Lauren Meister, the Mayor of West Hollywood spent approximately $600,000 to $700,000 on maintaining securities at this year’s event.

“West Hollywood Halloween Carnaval is always so much fun,” said Lauren Meister.

The Los Angeles County Sheriff’s Department were prepared for the Halloween Carnaval by hiring an additional 100 sworn personnel, which included arson investigators, K-9 units and members of the SWAT team. Prior to the event, law enforcement enacted a new rule that prohibited any reveler to enter with any sort of bags, except a transparent plastic bag.

“There’s always potential when you have that amount of people in a concentrated area that anything is possible,” Lt. Daren Diviak of the West Hollywood Sheriff’s station told NBC Los Angeles.

The Los Angeles Police Department also had a joint command post with the sheriff’s department and officers with the LAPD’s Counter –Terrorism and Special Operations Bureau to help maintain order in the city during the event.
