Police Commissioner: Killings in the Amsterdam Turkish Underworld are Worrisome
Chief Commissioner of the Amsterdam police, Pieter-Jaap Aalbersberg, has said that the conflicts within the Amsterdam Turkish underworld are worrisome. He added that this is not only a concern for Amsterdam, because killings also take place elsewhere in the Netherlands and in Istanbul. Aalbersberg said that besides the Turkish killings, there are also two other types of killings in Amsterdam: those related to Moroccans, concerning a load of cocaine which has disappeared, and those related to the older Dutch criminal networks.
