ATTACK victim Greg Vickers has suffered severe brain damage, say doctors.
The RAF serviceman was found lying in the street at Huntsman's Corner in Borras on Friday, September 16. He had suffered head injuries.
This week, as Greg was transferred from Walton's Critical Care Unit to the High Dependency Unit, his condition was described as stable but seriously ill.
His brother Luke said: 'Our family were told by consultants on Thursday that Greg has suffered severe brain damage and that he may never wake up.
'How can this happen? One day Greg is a fit and healthy 23-year-old and now we are told this shocking news.
'I cannot believe that someone has not provided information relating to this crime to the police.'
Officers from Wrexham CID have extended their efforts to find witnesses by distributing flyers in Wrexham.
'We expect that people may have seen Greg around and believe their information is not important because they didn't see the attack,' said Detective Inspector Neill Anderson. 'But we need to know where he was all night.
'We know he got a taxi around 2am from the top of Bradley Road near Bellevue Park. If you saw him making his way there, then tell us about it. If you saw him doing anything at all, even walking past you, in the missing hour-and-a-half between 2am and 3.30am, when he was found, call us.'
Anyone with information should call 0845 6071002 or Crimestoppers in confidence on 0800 555 111.
