A detainee who the police linked to Ridouan Taghi's network was able to make unlimited and uncontrolled calls to the outside world due to a blunder in the penitentiary in Krimpen aan den IJssel. According to the Algemeen Dagblad , it was a suspect who was a flight risk and had been placed in an extra strict prison regime.

The issue occurred in the period after September 2023, after the arrest of Ridouan Taghi's eldest son. In the Netherlands, dozens of suspects were then told that their GVM status had been increased (GVM stands for detainees with a flight and/or social risk).

This means that they will be placed in a stricter regime and will be monitored more closely. One of the restrictions is that they are allowed to make short calls and only under supervision. All telephone conversations are listened to live by security staff.

In the Krimpen aan den IJssel PI there are great tensions surrounding at least two men who have been convicted of liquidations. One of them was attacked by a group of fellow detainees in mid-December. Also - due to the actions of a guard - a detainee burst into someone's cell with a knife. The person in that cell has been under serious threat for several years.
