On Thursday, the Public Prosecution Service (OM) also demanded a life sentence on appeal against a "ruthless" Willem Holleeder.

The man is guilty of ordering five murders.

In a two-day requisition, the Public Prosecution Service explained how they believe Holleeder had a part in the murders of Cor van Hout and Willem Endstra, among others.

Evidence for this can be found in the statements of the Holleeder sisters.

The demand for life did not come as a surprise.

It was the demand that the Public Prosecution Service also asked the court for and also the sentence that was imposed on 63-year-old Holleeder last year.

According to the prosecutors, Holleeder had various motives, such as financial gain or because the victim, such as John Mieremet, had planned for his life.

"Murder is one of the most serious crimes in our country," the public prosecutor told the court in Amsterdam.

"No one has the right to dispose of someone else's life. Yet that is what the suspect has done."

"He has played for his own judge," the officer continued.

All this, according to the Public Prosecution Service, stemmed from "lust for power, envy and the pursuit of profit."

The Public Prosecution Service described Holleeder as a "master intriguer" who has deliberately chosen a criminal life.
