An armed policeman and two soldiers guard the shops on Rue Du Marche Aux Herbes on November 23, 2015 in Brussels, Belgium.

Salah Abdeslam, a prime suspect in November's Islamist attacks in Paris, probably evaded a police raid in Brussels on Tuesday, Belgian public broadcaster RTBF said on Friday after investigators found his fingerprints at the scene.

"According to our information, it is more than likely that he is one of the two individuals who escaped during the shootout," RTBF said on its website, referring to Tuesday's raid in which one Islamist gunman was shot dead by a police sniper.
