"We especially appeal to anyone who might have filmed or think they have photographed the suspect," a spokesman said, as prosecutors presented a video showing the man's escape route from the devastated departure hall back into central Brussels.
Two blasts ripped through the departures hall of Brussels' Zaventem international airport on March 22. Another explosion went off at the Maelbeek metro station near the headquaters of the European Union institutions.
Ibrahim Bakraoui and another attacker, Najim Laachraoui, detonated their explosives in the airport, while Khalid Bakraoui carried out the attack at the Maelbeek station.
