Mr Collier fell to the ground and hit his head, causing a bleed on the brain from which he died in hospital the following day.
Following an investigation by the Kent and Essex Serious Crime Directorate, Harris, of Buenos Ayres, Margate, pleaded guilty to manslaughter on Friday 12 February 2021. He was jailed for four years and nine months at Maidstone Crown Court on Friday 18 June 2021.
The fatal attack came after Harris accused Mr Collier of dropping cigarette butts on to his balcony, despite the butts being of a different kind to that the victim smoked.
Harris was overheard talking about the victim the day before the assault, saying he would ‘knock him out’ and ‘do him outside’.
Shortly after 5pm on Tuesday 6 October 2020, Harris entered the hotel’s communal hallway at the same time Mr Collier was coming in the front door.
Senior investigating officer Detective Inspector Garry Cook, of the Kent and Essex Serious Crime Directorate, said: ‘This case illustrates how violence arising out of the most minor of disagreements can lead to tragedy.
‘Officers acted quickly on the day of the assault and swiftly gathered the evidence which led to his guilty plea. Harris will now have time in prison to reflect on the impact of what he did that day.’
