Abrini, 31, is the man in beige wearing glasses, a blue hat and pushing a trolley that carried the largest of the three explosive devices through the airport on Tuesday morning.
CCTV caught him running from the scene shortly before two blasts went off in the departures lounge.
The announcement comes as shots were heard during a police operation in which a suspect has been "neutralised" in the Brussels district where a bomb was detonated on a train station just one hour after the airport blasts.
It is not clear whether Abrini is still at large.
The Morrocan-Belgian was well known to police who put an international arrest warrant over his head on November 24 — less than two weeks after the Paris attacks.
He had previously been spotted in the Renault Clio that was used as a getaway car when terror suspect Salah Abdeslam chickened out of pulling the detonator on his suicide vest.
And he was pictured with Paris massacre mastermind Salah Abdeslam on November 11 — two days before their assault on the capital.
It was later sensationally revealed that the sick terrorist staked out a British football ground before the cell tried to attack the Stade de France stadium after the attacks.
