The Belgian federal prosecutor’s office said the suspect, whose full name was not disclosed, was being held on charges of taking part in a terrorist group and terrorist murders.

His arrest took place on Tuesday, the prosecutor’s office said.

It said the suspect, a Belgian citizen born in 1985, had been in contact several times with Hasna Ait Boulahcen following the November 13 attacks in Paris, in which 130 people died.

Both Ait Boulahcen and her cousin Abdelhamid Abaooud, the attacks’ suspected ringleader, were killed when French police besieged their hideout north of Paris.
