California marijuana delivery man says he was robbed by ninjas

Police in southern California were investigating Monday a man's claim that he was robbed by two ninjas while he was delivering medical marijuana.

The unidentified man told police that he was making a delivery Friday night in West Covina, Calif., when he was approached by two men in ninja costumes with masks covering their faces, KTLA-TV reported.

He said the two robbers brandished batons, causing the delivery man to flee and drop a bag filled with marijuana and money. The ninjas grabbed the bag and fled the scene.

West Covina Police Department Sgt. Travis Tibbets said the two men were still at large Monday and no arrests have been made.
