The UK Foreign Office has confirmed that two British nationals were injured in the fatal bomb attacks in Brussels on 22 March. David Dixon, an IT programmer from Nottingham has also been listed as missing.
Dixon, who has lived in Brussels for the past 10 years with his partner and their young son, has not been seen or heard from since the attacks on Brussel's airport and metro. He travels to work every day using the city's Metro.
Since the attack, he has not answered his phone or made contact with his family. He has not arrived at his office either. The BBC reported that his partner, Charlotte Louise Sutcliffe from Creswell, Nottinghamshire, has been frantically driving from hospital to hospital in Brussels to locate him.

A friend Rachel Stevenson in London, posted a picture of Dixon and his son on her Facebook page, appealing for information. "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. Please can you share this post and if anyone sees him, get in touch with Charlotte Louise Sutcliffe."
