Over 250,000 people across Southern California were forced to evacuate their homes as wildfires ravaged the coast.
Ventura County Sheriff's Office announced Monday, November 11, that it was dispatching teams of law enforcement officers to help handle looting in evacuated neighbourhoods.
"We have experienced some looting activity during the past two days. Southeastern Ventura County is within a declared disaster area. People need to stay out of the area to let public safety crews do their work," the sheriff's department said in a press release.
"People found in areas where they do not belong will be contacted by law enforcement and may be arrested."
Several celebrities homes were among those destroyed, including the Kardashians, Miley Cyrus and Gerard Butler.
Pink and Carey Hart were also among those forced to flee their $110million home in Malibu, which is believed to have survived the wildfires.
