A few months ago there was a problem with 3 Willems..
The three Willems were:
Willem Holleeder: One of the biggest criminals in the Dutch Underworld today. He was one of the kidnappers of the famous Freddy Heineken in 1983.
Willem Endstra: Willem Endstra was a real-estate manager and als known as 'banker of the underworld' (as MMFloors said in his post). He laundred money for the underworld.
Willem van Boxtel: He was the president of the Hells Angels in Amsterdam.
Willem Holleeder was said to extort Endstra. Endstra wasn't so pleased with this and opposed Hells Angels-president Willem "Big Willem" van Boxtel to kill Holleeder for -I believe- 1 million euro.
But Holleeder found out about the plan and Endstra got whacked on the 17th of May (2004) in the middle of Amsterdam on broad-daylight.
Big Willem was forced by his underlings (forced by Holleeder?) to leave the Hells Angels. He left the organization in what they call 'bad standing'.
Just to give you a little bit history-information about the things that are going on at the moment...
