Yeah, probably as contacts to the groups already operating in GB. GB already has a large crime scene. Homegrown British 'Firms', Yardies, Nigerians, South Asians, Triads, Black British and Somali gangs, Turkish and Kurdish clans, Albanian mobs,...it's already overpopulated there lol.
And regarding the homegrown crime firms : the Adams from Islington, the Hunts from Canning Town, Liverpudlian and Manchester clans,...I would never ever mess with those guys
