Russian, 52, attacked friend, 47, after penis-measuring competition

Angry at losing out to his friend, he hit him over the head with an axe

The 52-year-old then grabbed his friend’s manhood and chopped it off

The elder man grabbed the axe and hit his friend over the head with it, before chopping off the man’s penis, it was alleged.

A police spokesman said: ‘Over two days the men were binge drinking, which led to a violent argument.

‘When words were exhausted, the attacker pulled out an axe and first struck the opponent on the head, then cut off his manhood.’

Neighbour called the emergency services after hearing the man’s pained screams.

Reports said it was the man judged to have the smaller genitals who wielded the axe.

The men have known each other since childhood and live in the village of Nikolsk. They were not named.

The older man has been charged with inflicting a ‘grave injury’ on his friend.

He faces up to eight years in jail if convicted.
