KEN STANDARDS & RUTGER LOVENS
After 35 years, ‘the Giant’ of the dreaded Brabant killers gang has finally been de-masked. According to the judiciary he is a deceased former national policeman from Aalst and a former member of the Group Diane elite unit.
A year ago, a relative of the Aalst man C.B. contacted the federal judicial police about his past in the Brabant killers gang. It brought bloodshed between 1982 and the end of 1985 with terrorist attacks on, eg, department stores. They killed 28 people. “Just before he died at 61 years old in May 2015, he told his secret,” said the relative. “He was the Giant of the Brabant killers.”
According to Wikipedia, ‘the Giant’ may have been the leader of the Brabant killers. That policeman cum Brabant killers Giant had extreme right political vieuws, according to Belgian daily yHet Nieuwsblad.
The Brabant killers gang has been connected before with some policemen, with NATO and with the Belgian extreme right. The supposedly anti-terrorist elite unit Group Diane has been connected to the Brabant killers before, by Jef Vermassen, lawyer of Brabant killers victims. The Brabant killers were far-right terrorists, Vermassen says.
