The two most likely scenario's at this moment is that either someone got his hands on cheap Heroin and wanted to make a quick sell or that someone was ripped and sold a large quantity of Heroin and now wants to make some money off that. Either way, in the Netherlands you apparently hardly get rid of heroin, whereas coke is sold for much higher prices much easier.
