Chilling new images have emerged of suicide bomber Bilal Hadfi, who blew himself up outside the Stade de France during the deadly Paris attacks on Friday, which killed 132 people.
The arrest came hours after prosecutors revealed that Abdeslam's fingerprints were found in an apartment in another part of Brussels earlier this week following a raid in which a suspected IS militant was killed.
The 17-minute video, dubbed 'Paris Has Collapsed', features the final words of the killers behind the Paris attacks last November.
The 28-year-old is believed to be linked to thwarted attacks on a high-speed train from Amsterdam bound for Paris in August, as well as a planned attack on a Parisian church.
