A British man, thought to have been on the metro system at the time of the Brussels attacks, has been reported missing by his friends on social media.

David Dixon's partner Charlotte Sutcliffe says that David, originally from Hartlepool, did not arrive in his office on Tuesday morning in the Belgian capital.

His friend Simon Hartley-Jones said "he's not been seen or heard since yesterday morning."

He added "We're clinging on to the hope that he is somewhere and he is being cared for."

Friends of David Dixon have set up a search appeal for him on Facebook and Twitter.
