The man who raped and murdered young Utrecht woman Anne Faber last year should be jailed for 28 years, followed by compulsory treatment in a psychiatric prison, the public prosecution department said on Tuesday.

The prosecutor said he had decided not to call for life imprisonment, because this could lead to Michael P being released from jail after 25 years without undergoing proper treatment.

‘This would be totally irresponsible, given that P is guilty of very serious sex crimes,’ the prosecutor told the court on the second day of P’s murder trial.

In addition, the prosecutor said, P had attacked five people in the Pieter Baan psychiatric clinic where he had been sent for observation. ‘We concur with the view that P has signs of diminished responsibility and agree that he should be sentenced to tbs (psychiatric prison),’ the prosecutor said.

Anne disappeared on September 29 after going out for a bike ride. Her body was found two weeks later at a spot identified by P.

P told the court on Monday that he had killed Anne to stop her shouting for help and had been planning to ‘let her go’ after raping her, website Nu.nl reported.

P was jailed for 11 years in 2012 for the brutal rape of two teenage girls and for a string of robberies but had not been sent to a psychiatric prison for treatment because he had refused to cooperate with a psychiatric assessment prior to his trial.
