An aircraft engineer fed up with the noise outside his hotel was brutally kicked in the head after asking a group to be quiet.
Mr Nesmelov was punched to the ground, kicked and stamped on in the attack by the group, which allegedly included professional boxer and martial arts trainer Daniil Gritsay.
According to police, Mr Nesmelov travelled to the town of Millerovo in south west Russia for a business meeting and had asked a group that had gathered outside the hotel to make less noise.
Half way through the violence one of the group started filming their victim, whose face was covered in blood, on their mobile phone.
