Story highlights Police seek suspected third man in Brussels Airport bombing

Man ditched raincoat along his walk away from bomb scene, authorities say

Police appeal for information from the public

(CNN) The suspect was wearing a fishing hat, rolled-up shirtsleeves and a raincoat that cannot be found.

And he left the scene of the March 22 terrorist bombing at the Brussels Airport on foot. As police swarmed over the area, he just walked away.

Belgian police, seeking help from the public in finding this man, released a series of surveillance images Thursday that show the suspect leaving the airport in Zaventem, heading west into the Brussels district of Schaerbeek, over the course of two hours following the bombings.

Police say this image shows a suspect in the March 22 bombings walking from the Brussels Airport.

This suspect is the same man shown in a previously released surveillance image taken at the airport before the attack -- a man wearing a dark hat and pushing a luggage cart next to two other men who police say killed themselves in the bombings -- the Belgian federal prosecutor's office said.

The bombings at the airport check-in area and, an hour later, at a Brussels subway station killed 32 people and injured more than 300 others.
