Family knocked out in Thai street attack
Three members of a British family have been punched and kicked unconscious in a street attack in Thailand.
Two men and a woman needed hospital treatment after the assault in the tourist resort of Hua Hin during the Thai New Year celebrations.
CCTV footage shows a brief argument taking place before the attackers punch and kick the victims.
The Bangkok Post reported that four men had now been arrested.
The attack took place on 13 April but details only emerged after the CCTV footage appeared online.
The three victims have been named as Lewis and Rosemary Owen and their son John Owen, by the Tourism Authority of Thailand (TAT).
Mr Owen, 68, and his 43-year-old son both suffered blows to the face and body.
The footage shows Mrs Owen, said to be aged 65, knocked to the ground by a punch. When she sits up again an attacker delivers a kick to her head.
The images show a large crowd watching the unfolding scene in the busy street as all three are beaten unconscious and left on the pavement.
Police spokesman Chaiyakorn Sriladecho said the attack started after the son accidentally bumped into one of the Thai men.
He told the Bangkok Post: "The men say they are sorry and that they wouldn't have done this if they weren't drunk."
The father and son required stitches for head injuries, while the mother remains in hospital with serious head and eye injuries, the spokesman said.
In the video, a passerby appears to come under attack from several men after trying to intervene in the melee.
A contributor to the Hua Hin internet forum said they had tried to the help the family whom they recognised from a nearby bar.
They wrote: "Within 20-30 metres of leaving the bar the Thais were punching the 65-year-old lady in the face!! The elderly gentleman was down on the floor and their son was beaten very badly!!!
"At this point I caught up to the scene and pushed one of the youths away from the woman...
"I got severely punched and kicked for my troubles, but felt the need to protect this frail lady.
"The three of them are still hospitalised and I will need cosmetic dental work done."
The Foreign and Commonwealth Office (FCO) said it had no information on the family's condition.
An FCO spokeswoman said: "Our staff have been in contact with the family to offer assistance and will remain in contact with the local authorities."
