Syria's Olympic Committee General Mowaffak Joumaa has been refused a visa to the London 2012 Games.
It was expected earlier in June that General Joumaa would be denied entry into the UK because of his connection to the Syrian military and President Bashar al-Assad's regime.
The BBC claim the decision was made during a recent meeting between senior officials from the Home Office, Foreign Office and Department of Culture, Media and Sport.
The Home Office is responsible for carrying out background checks on behalf of the International Olympic Committee (IOC) and advises the committee on whether an applicant is suitable for accreditation.
General Joumaa vowed he would complain to the International Olympic Committee (IOC) if his visa is denied.
He said last week: "If anyone was blocked because of their military background, that would be unfair. Anyone who has a military background in Syria, they are an ordinary citizen of this country.
"You have seen how much Syria enjoys security and safety. We are a peaceful country. The Syrian people have love in their hearts for the British people."
Already the Syrian charge d'affaires in London has been expelled as figures within British politics continue to condemn the attacks in Syria.
Foreign Secretary William Hague has likened the recent massacres to those in Bosnia in the 1990s while Prime Minister David Cameron condemned the killings as "brutal and sickening".
An IOC spokesman said: "At this stage we have not yet received any official approach on this issue and it would be premature to comment on any individual cases."
