Emwazi, who was identified in reports as the ISIS militant Jihadi John, was detained by Tanzanian authorities along with two university friends when they arrived at an airport in Dar-es-Salaam. There, Emwazi was reportedly told the UK Government could be behind them being refused entry into the country.

Tanzania's home affairs minister Mathias Chikawe said the reason Emwazi and two friends were turned away was because they were "very drunk".

The newspaper reports that Emwazi and his companions had embarked on a ten-hour drinking session during the flight from Amsterdam.
