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.

Brussels attack survivor: ‘Part of my hip was missing’

The man in the images released Thursday is one of two seen in surveillance footage that day who authorities say are at-large suspects. The other man was spotted at the Maalbeek metro station, holding a large bag, before the bombing there.

Police: Suspect got rid of his raincoat

The airport suspect started his walk after the airport bombings at 7:58 a.m., Belgian authorities said Thursday. Images show he went past a hotel and cut through a rental-car parking lot, eventually walking south through the center of Zaventem, which is home to the airport.

He then walked southwest toward Brussels, appearing near a square in the city’s Schaerbeek district by 9:42 a.m. ET, the prosecutor’s office said.

Surveillance footage shows him for the last time at 9:50 a.m., when he was at an intersection just south of another square, Place Dailly, otherwise known as Daillyplein.

He initially was wearing a fishing hat and a light-colored raincoat, but the newly released images show he ditched the raincoat somewhere along the way, authorities said.

Airport surveillance shows the man, right, near bombers Najim Laachraoui, left, and Ibrahim El Bakraoui.

Police want to recover the recover the garment, saying in a statement Thursday “it may hold important traces.”

Detention of Abdeslam and alleged accomplice extended

Also Thursday, a Brussels court extended the detention of terror suspects Salah Abdeslam and Ahmed A. – alias Choukri – according to a statement from the Belgian federal prosecutor.

Earlier, Abdeslam’s attorney, Sven Mary, had told reporters it would take weeks to extradite Abdeslam – a suspect in the November terrorist shooting and bombings in Paris – to France following a hearing.

Abdeslam is suspected of having played an important role in planning the November 13 attacks that killed 130 people in the French capital.
