Following the bust of the Assyrian crime family Y. for their involvement in large-scale cocaine trafficking in the Antwerp region, the mayor of Antwerp claims that there are at least 5 more clans they know about currently involved in the local cocaine business. This includes 3 Moroccan groups based in the Borgerhout district as well as an Albanian group.

Furthermore it has been stated that the Antwerp law enforcement tends only to bust the local clans after they already hit their peak and often already quit their involvement in cocaine trafficking. It's said that the Assyrian group based around the Y. clan haven't played a role of significance in the last year. It's rumored that law enforcement had enough ammunition to bust the Y. group years ago while they were at their peak, but opted to wait instead.

Same scenarios have been noticed with other Antwerp cocaine groups before; such as the Borgerhout-based Moroccan crime clan S. ("The Mixers"), another Borgerhout Moroccan clan Z. or the Greek group based around Eleftherios P. (the "Greek Godfather of the Sint-Paulusplaats"). In all of the cases law enforcement declined to intervene until the groups got very big. Eleftherios P. for instance wasn't put away until he got to the age of 78 even though they apparently had files on him dating back to the 80's.
