Brussels — Belgian authorities say several arrests have been made in relation to the Brussels attacks, one day after they called on the public to help look for a key suspect who was involved in the March 22 bloodshed that killed 32 people.

The prosecutor’s office said Friday it made “several arrests” but refused to provide more information.

Belgian broadcaster VRT, citing sources it did not identify, said Paris attacks suspect Mohamed Abrini was among those arrested.

Abrini is the last identified suspect still at large from the Nov. 13 attacks in Paris which killed 130 people. He is a 31-year-old Belgian petty criminal and is believed to have traveled early last summer to Syria where his younger brother died in 2014 in the Islamic State group’s notorious francophone brigade.

He has been on the run since the Nov. 13 attacks but never resurfaced after the emergence of surveillance video placing him in the convoy with the attackers headed to Paris. He had ties to Abdelhamid Abbaoud, the ringleader of the Paris attacks who died in a police standoff on Nov. 18.
