Carey Hart, 43, issued the warning to looters in an Instagram post on Tuesday
He wrote: 'There have been sightings of looters breaking in to homes. Well, if you are a looter, think twice if you are heading back into malibu (sic)'
The caption was paired with an undated photo of a group of men holding firearms with a sign that reads: 'Looters will be shot on site'
Hart and wife Pink were among the 250K people forced to evacuate their homes in Southern California as the Woolsey and Hill fires torched nearly 100K acres
The couple's $110M beachside home in Malibu reportedly escaped the flames
Officials on Monday announced that law enforcement has been dispatched to evacuated areas following several reports of looting
