Israeli police are on the lookout for a thief with a super-sized chocolate craving.

The robbers broke into a factory in the northern Israeli city of Haifa late Monday and walked away with nearly 100 tons of chocolate spread.

Police spokesman Micky Rosenfeld said such a large heist indicated it may have been an inside job and police were searching the area of any traces of the sweet stuff.

Moshe Veidberg, one of the company's owners, told the Israeli daily Yediot Ahronot it would require five large trucks to transport the stolen chocolate, which he valued at roughly $415,000.

He said the company's alarm system was deactivated and its surveillance footage stolen as well, leaving the fate of the creamy chocolate a mystery.
