Brussels bombing suspect let go as new 'man in hat' CCTV footage released

Belgian police have released a man that they had initially charged with "participation in a terrorist group" and "terrorist killings" in connection with the Brussels attacks on the same day that they revealed new CCTV footage of another suspect.

Faycal C, who was the only person charged in connection with last week's attacks, was released due to "lack of evidence", prosecutors said.

It comes as US Republican presidential frontrunner Donald Trump warned Britain and Europe are "not safe" following the recent terror attacks.
