Missing Briton 'On Metro At Time Of Attack'

Family and friends of a British man reported missing after terror attacks in Brussels are appealing for help to find him.

David Dixon, originally from Hartlepool, is thought to have been using the Belgian city's subway system when a blast ripped through a train at Maalbeek metro station on Tuesday - barely an hour after twin explosions at Zaventem Airport.

It is understood that Charlotte Louise Sutcliffe, Mr Dixon's partner, has not heard from him since the terror attacks killed at least 34 people and left about 200 more seriously injured.

Simon Hartley-Jones urged Twitter users to share an appeal poster, writing: "My very good friend David Dixon is missing in Brussels. Please retweet to help find him."

The poster featured a picture of Mr Dixon and a message asking people to contact Ms Sutcliffe if they see the commuter.

The message added: "He was in the metro system, he didn't arrive to his office and still we haven't reached him."

In a Facebook appeal, Rachel Stevenson wrote: "My friend David Dixon was on the metro at the time of the blasts and is still missing - he hasn't been able to contact his partner.

"If you know people in‪ Brussels, please can you share this post and if anyone sees him, get in touch with Charlotte Louise Sutcliffe."
