The organization is allegedly responsible for stealing work vans from plumbers, painters, landscapers, and construction workers, which contained thousands of dollars of tools and equipment. These suspects would eventually offload the stolen tools and equipment, sell the stolen vans, and in some cases chop up the stolen vehicles and sell them as scrap metal.

25 vehicles have been recovered in the investigation, with many of the vehicles being stolen out of the South Bay area, which include Long Beach, San Pedro, Redondo Beach, as well as Lakewood, Norwalk, Paramount and even Las Vegas, authorities said.
