BRUSSELS (AP) — Belgian authorities say several arrests have been made in relation to the Brussels attacks.

The prosecutor's office said Friday it made "several arrests" Friday, one day after it called on the public to help look for a key suspect in the March 22 attacks that killed 32 people.

The prosecutor's office refused to provide more information.

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