Paris attacks suspect Salah Abdeslam | Belgian Federal Police/EPA Salah Abdeslam was part of Brussels bomb plot Detonators found in a Brussels apartment link Abdeslam to the attacks on Brussels.

The Paris attack suspect Salah Abdeslam, who was arrested in Brussels last Friday, was supposed to have taken part in the bomb attacks that hit the Belgian capital on Tuesday, according to a senior Belgian official.

Abdeslam's fingerprints were found in an apartment in the Brussels neighborhood of Forest that was raided by law enforcement authorities last week, where officers also found detonators that were probably meant to be used in the attacks, said the official, who was speaking on condition of anonymity.

Belgian Foreign Minister Didier Reynders had warned after Abdeslam’s capture that the alleged Paris terror suspect was preparing further attacks.

“He was ready to restart something from Brussels, and it’s maybe the reality,” said Reynders to a group of top security experts at a German Marshall Fund conference in Brussels on Saturday. “We found a lot of weapons, heavy weapons in the first investigations, and we have seen a new network of people around him in Brussels.”
