Police say small groups composed of up to five refugees roam the beach looking for easy pickings. Young lovers or teens in the water are the preferred targets, but the main goal is to find a bag or something else lying around that is easy to grab and then sell at the city's Central Bus Station. Police describe the gangs' activities as follows: they begin by surveying the beach. The moment one of the thieves spots a likely item, he signals his buddies. Then the group strolls toward the promenade to plan the theft.
