A 51-year-old man’s genitals were hacked off while he slept after a night of drinking with friends in a ‘horrific cannibal attack’, according to reports.

Moses Wanyoike only realized his genitals were missing when he went to the toilet and looked down after spending the night at a friend’s house in Muranga, Kenya.

Those who lived nearby were called to join in the hunt for the missing piece so it could be reattached but no trace could be found.

Locals have suggested his attacker ‘later munched on his body parts,’ according to news site mpasho.

‘I was among the people who searched for the missing part of his genitals,’ one member of the search team told Kenya’s Daily Nation.

‘We hoped we could find it and take it to the hospital in time for it to be stitched back on. It is unfortunate that did not happen.

‘He was in a total mess. He was bleeding profusely and had his pair of trousers torn from the back.’

Wanyoike spent six hours drinking with friends before heading back to one of their homes at around 2am.

During the journey home one friend repeatedly mentioned wanting to circumcise Mr Wanyoike but he dismissed it as a bad joke.

But just hours later neighbors were woken up to the sounds of his screams – although he says he didn’t realize the damage that had been done.

‘Throughout the journey home he kept telling me that he would circumcise me. I treated it as a bad joke. I thought he was drunk,’ Wanyoike told K24 Digital.

Local county assembly representative James Karanja, who raced Mr Wanyoike to Level Five Hospital, Murang, said he was told a man in his ward had been ‘Bobbitted’.

Karanja, who referred to the phrase coined in 1993 after American Lorena Bobbitt cut off hubby John Wayne’s Willy, suggested drugs might be to blame for the attack on Moses.
