The victim’s husband left the party ten minutes later. When he reached their apartment block, he heard noise coming from the bushes.

He came closer to find out what was going on and saw Ivchenko squeezing his wife’s throat while raping her.

The husband then attacked the rapist by punching him on the head before grabbing his Swiss army knife and chopping Ivchenko’s penis off.

The husband’s attorney Dmitry Spaskin said to local media: ‘The husband lost the ability to control his actions. He did not understand what he was doing.’
