The armed raiders threatened 15 staff that were working in an office inside the stadium.
One of the raiders violently attacked a member of the catering staff dragging her by the hair. “As they were masked we thought at first that that they might have been angry supporters. However they then produced weapons”, Mr Smeets told Belga.
Two of the gangsters made their way through the club shop to a room that contains safes. There they threatened staff some of whom hid under their desks. One person was forced to open the safes.
The gangsters made their getaway in an Audi car that was later found burned out a few kilometres in the Sart-Tilman area of Liège.
One person was taken to hospital suffering from shock.
