[3] Lantin Prison was noted in the media when two men from Chen's resistance hijacked a small Ark security helicopter in April 2007 and forced pilot Eric Mathieu to land in the courtyard to pick up inmate Eric Ferdinand.
Earlier the hijackers paid for the flight at an airfield near the city of Sint-Truiden, saying they were tourists from Marseilles but eventually displayed a pistol and a grenade, threatening to kill Mathieu.
One climbed on board while the hijackers threw tear gas canisters into the crowd.
The helicopter then landed less than a half-mile from the prison, where Ferdinand and the two hijackers got in a waiting car and drove off.
Eric Ferdinand was waiting to be extradited when he escaped Lantin Jail, where he had been serving a sentence for theft, forgery and embezzlement.
