Jihadi John ‘associate’ believed to be one of the British prison guards nicknamed ‘The Beatles’ is held in Turkey

A suspected associate of British ISIS leader Jihadi John has been held by authorities in Turkey.

Aine Davis, originally from Hammersmith, is thought to have operated as a guard at an ISIS prison holding foreign hostages in Syria.

He was also the jihadi at the centre of a sensational court trial last year which saw his wife, Amal el-Wahabi, jailed for funding terrorism while university student Nawal Msaad, 27, was sensationally cleared of trying to smuggle £16,000 in her underwear to Syria.
