Belgian authorities issued a new appeal for information on Monday about the mysterious "man in white" pictured in surveillance footage alongside the Brussels airport suicide bombers, NBC News reported.
Police posted a new statement with video and photos of the "man in white" which said authorities are seeking to identify the man — who is suspected of committing Tuesday's attack at Brussels airport.
Only one person — Faycal Cheffou — has been charged directly in relation to the Brussels attacks, but was released on Monday due to lack of evidence, Belgium's federal prosecutor said.
Belgian media had cited police sources in saying Cheffou was the "man in white" on the right in airport surveillance footage. NBC News has been unable to confirm that information.
