Authorities in Brussels are asking for the public's help to find the man who was with two of the March 22 terrorists that attacked an airport in the country.
FOX's Simon Owen from the European bureau:
The suspect has become known as the man in the hat, simply for his choice of clothing.
He was seen on security footage walking through Brussels Airport with two men who went on to blow themselves in the check-in area.
But, two and a half weeks later, it seems authorities still don't know who he is. Prosecutors just releasing a series of pictures tracking the suspect running from the airport and walking into Brussels.
They point out he ditches his jacket at one point and asking if anyone may have found that in a trash can.
