The night saw him visit two bars, before being asked to leave a nightclub by bouncers because he'd 'consumed enough alcohol'.He then visited a takeaway, before falling asleep for two hours in a shop doorway.
Of particular interest is believed to be 'Oriental-transvestite', a user of Fab Swingers who claims to live in East London, not far from the Millennium Dome.
Mc Keague's unconventional sex life has prompted speculation that his disappearance could be linked to a casual liaison on the night he vanished.
Yet a long shadow has now been cast over these scenes of domestic bliss.
For the man in the pictures is Corrie Mc Keague, the RAF serviceman at the centre of perhaps the most bizarre manhunt in recent years.
However, the police appear to take a different view, saying that Mc Keague's use of Fab Swingers is now 'part of our investigation'.
It emerged yesterday that they are interviewing contacts the couple made on the site.Dated April 15, 2016 (when he was supposedly dating Oliver), it was written by a 28-year-old woman from Cambridge using the moniker 'pinupchick88' who describes herself as 'quite brutal'.She recalled their encounter by saying that Mc Keague 'turned up looking and smelling amazing, didn't take long for me to take his clothes off, and he didn't disappoint!Mc Keague had been active on a website called Fab Swingers since 2014, when he'd created a profile saying he wanted to arrange anonymous liaisons with straight and lesbian couples and single women aged between 18 and 60.The site listed among his interests 'blindfolds', 'making videos', 'group sex' and 'SM [sadomasochism]'.Having met via a dating website, they had formalised their relationship in June, in a series of images posted on the photo-sharing network Instagram.One showed them cuddling in bed, with the 23-year-old man (who'd just departed for a fortnight's summer holiday) playfully grabbing his scantily-clad, 21-year-old companion by the neck.'My man and I having cuddles before he left,' she wrote. I love you baby xxx.' Another image showed the lovers holding hands, fingers intertwined, while the young man's pet puppy, a black cross-breed called Louell, rested his chin on her naked thigh: '#mummydaddyandbaby #familylife #myboys' read her caption.That all suddenly changed on January 10, when Oliver gave a TV interview making the shock announcement that they were not just a couple, but that she was pregnant with his child.The plot then thickened considerably on Thursday when it also emerged that both Oliver and Mc Keague had for some time been living an astonishing double life, trawling the internet looking for casual sex with strangers.A huge PR campaign, run by his family, and with thousands of supporters on social media, has failed to shed any light on the mystery.Adding to the intrigue, meanwhile, are recent revelations about Mc Keague's relationship with his 21-year-old lover, April Oliver.
