Family backs Portsmouth's Christmas anti-violence video
The mother and brother of a sailor who died after being punched while on a night out in Hampshire are backing a Christmas anti-violence video campaign.
Kyle Bartlett, 21, from Bordon, was injured in a fight at Portsmouth's Walkabout bar in May 2009.
Ann Bartlett agreed to switch off her son's life support machine the next day when tests showed he was brain dead.
A video highlighting the One Punch Can Kill campaign by Safer Portsmouth Partnership has now been released.
Alcohol-fuelled violence has resulted in the deaths of two men, including Mr Bartlett, in the city over the past two years, according to Portsmouth City Council.
Ms Bartlett joined forces with the Safer Portsmouth Partnership in May 2011, around the second anniversary of her son's death, to launch the One Punch Can Kill campaign.
A spokesman from the council said the campaign's new video, which features family footage of Mr Bartlett, aims to remind people that too much drink "can turn a good night into a tragic disaster".
Jack Bartlett, 21, said losing his brother had been "utterly devastating" for his family.
He added: "People need to realise that drinking excessively and punching someone, just once, can ruin their life as well as ending someone else's.
"I cannot let other people go through what myself and my family are going through now."
Mr Bartlett was a marine engineer technician on board HMS Liverpool.
Royal Marine Ben Scott, 22, of Portsmouth, was tried for manslaughter but cleared by a jury last year.
