In a SSP area in a chemical plant, the health supervision found two barrel products without final packaging when he was cleaning the tool warehouse. He locked the door when he finished his work and decide to take the products next day. In next day morning, he found there were just two shells and the lock of the warehouse had not any breakage. Obviously, it was a company internal occupation behavior.

We found it was a gang crime. The main suspect was the leader of a work team in the SSP area. He stole the products with the help of other 2 workers and sold the products to the black market. Finally, the client reported to the local PSB with the evidences we collected. The 3 thieves beard their legal liability.
