Jihadi John suspect Mohammed Emwazi was refused entered to Tanzania in 2009 because he was "very drunk," it has been reported.
Emwazi, the masked Islamic State (IS) fighter who has appeared in the video of the murders of its Western hostages, was reported to have been stopped at the airport in Dar-es-Salaam by border officials and was told the British Government could have been behind the refusal to let him enter the country.
But Tanzania's home affairs minister Mathias Chikawe told The Times (£) that Emwazi and two friends were actually turned away because they were "very drunk".
IS, also known as ISIS or ISIL, claim to be devout Muslims, though the consumption of alcohol is forbidden in Islam.
Mr Chikawe said: "They were refused entry because they disembarked from the plane very drunk. They were insulting our immigration staff and other people."
He added: "There was no information from anywhere that they were criminal suspects."
The paper claims one the trio was fellow Briton Ali Adorus, who is currently being held in an Ethiopian prison after being convicted of terror offences.
They were held at a police station overnight and put on a flight to Amsterdam the next day, where Emwazi claimed he was questioned by "Nick, from MI5".
Advocacy group Cage recently released an audio recording of an interview they claimed to be with Emwazi in which he said he was threatened by the agent during questioning at Schipol airport in Amsterdam.
He said the agent had tried to "put words in my mouth", adding: "'We are going to keep a close eye on you, Mohammed. We already have been and we are going to keep a close eye on you' - threatening me."
Emwazi claimed the agent accused him of trying to reach Somalia for terrorism training when he had tried to head to Tanzania - something he denied, insisting he was going on a safari trip.
Two charities have agreed not to fund a group which sparked controversy when it claimed the man unmasked as the militant Jihadi John had been driven to extremism after harassment from MI5.
Cage, which describes itself as an independent advocacy organisation campaigning against the "war on terror", last week described Emwazi as a "most humble young person" and suggested he had been poorly treated by security services with the result that he looked for "belonging" elsewhere.
The group, which is not a charity, received almost £400,000 in grants since 2007 from The Joseph Rowntree Charitable Trust and The Roddick Foundation.
The Charities Commission, which said the comments from Cage on Emwazi had "heightened concerns" about grants being awarded to the group, has now confirmed both charities have agreed not to fund the organisation again.
The hostages murdered in IS videos he appeared in include the American journalists James Foley and Steven Sotloff and British aid worker David Haines and taxi driver Alan Henning.
