More has been revealed about the man who stabbed an Albert Heijn supermarket worker to death on Tuesday as communication failures about his record come to light.

In early June Jamel L  appeared in court on a charge of threatening behaviour but the court denied the public prosecutor’s request for an evaluation at the Pieter Baan psychiatric facility.

Crucial information about the man’s history, including a period in a psychiatric prison (TBS) in Curaçao and convictions in Britain for violence, was missing from the file made available to the court.

It has since emerged that in 2018 then legal protection minister Sander Dekker rejected a request from the Curaçao court to continue the psychiatric treatment regime in the Netherlands, broadcaster NOS reported.

“Providing information is a matter for the defence and the public prosecutor, “ a spokesman for the court told RTL Nieuws. A different outcome could have been possible had the judge known about the man’s past record and contained clear warnings from judges abroad, he said.

It is not clear why the information was missing. “We are investigating this thoroughly,” a spokesman for the prosecution office said.

It has also emerged that L threatened council workers in The Hague earlier in the month when he asked for financial support and a place in a homeless shelter.

He showed aggressive behaviour on both occasions, which had been reported to police at the time, mayor Jan van Zanten said. The next day, on June 13, the council put a scheme in place to handle complex cases.

Jamel L killed the 36-year-old Albert Heijn worker a week later in an apparently random attack minutes after the shop had opened its doors. He is being held on a charge of murder or manslaughter.
