Abdeslam and his two accomplices were ordered to repay the 70,000 euros ($79,000) in cash they stole from government employees last February as they were carrying the money to a bank, the RTBF said.
The 29-year-old Salah Abdeslam is awaiting trial for his role in the bomb-and-gun attacks by Islamists in Paris three years ago that killed 130 people. He was jailed for 20 years in April for a shootout with Brussels police in March 2016.
The deadliest terrorist attack occurred in France on November 13, 2015, when gunmen killed 130 people and injured over 350 others in Paris' northern suburb of Saint-Denis in a series of coordinated attacks. Collomb characterized the attack as "the first case of mass murder" in France.
