Mohammed Emwazi, believed to be the masked Islamic State fighter who has appeared in a series of beheading videos, was reportedly refused entry to Tanzania in 2009 because he was drunk and made insults, rather than due to a tip-off from security services.

Emwazi, who has come to be known as Jihadi John, 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 said the reason Emwazi and two friends were turned away was because they were “very drunk”, the Times reported.

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 trio, one of whom the paper claims was fellow Briton Ali Adorus, who is currently being held in an Ethiopian prison after being convicted of terror offences, 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.
