The so-called Arabaci-Clan reportedly controlled the bouncer scene of the night clubs in Cologne's entertainment district, the Kölner Ringe, and his gang of bouncers reportedly befriended girls in order to exploit them as prostitutes.
In 2004 the Turkish gang leader Necati Arabaci was sentenced to 9 years in prison for pimping, human trafficking, assault, extortion, weapons violations and racketeering.
