Police released new images Thursday showing the so-called "man in white" behind the Brussels Airport bombing and appealed for help from the public in tracing his escape from the scene of the attack.
Prosecutors in Belgium confirmed that the unidentified man was still on the run and said he ditched his light-colored jacket in the minutes after the bombing.
Surveillance video showed him walking past the nearby Sheraton hotel and an Avis car rental parking lot. He was later seen in the nearby town of Zaventem wearing just a bright shirt with rolled-up sleeves.
Federal prosecutor Eric Van der Sypt said that authorities were especially appealing to people who might have filmed or photographed the man.
Earlier video of the suspect at the airport showed him wearing a dark hat, and glasses while pushing a luggage cart loaded with a black bag.
Two other men next to him in that video — Najim Laachraoui and Ibrahim El Bakraoui — blew themselves up in the attack. Bakraoui's brother, Khalid, carried out an attack in the Brussels subway on the same day.
Police sources had at one point named the man in the hat and light jacket asLaachraoui, a suspected bomb maker in the November 13 attack in Paris.However, officials later corrected that and said Laachraoui had died in the attack.
Separately, a court in Brussels earlier Thursday extended the detention of other suspects linked to the March 22 attacks - Mohamed B., 37, Yassine A., 30, and Aboubaker O., 28. They were arrested March 27.
