THE family of a Keighley teacher left in a coma after being brutally attacked in Thailand have endured more frustration after the expected verdict on his accused assailant was delayed again.

Parents Andrew and Adele Pickles had hoped to hear on Tuesday (Aug 19) what a Thai court had decided on British expat Sean Henry Tinsley, from Wolverhampton, who is alleged to have struck Adam Pickles with an iron bar in the resort of Pattaya in May 2012.

The road rage attack is believed to have been triggered by an incident in which a car was scraped.

However, the couple were shocked to hear that the verdict was being postponed again because important legal documents had been sent to the wrong court. They have now been told they will have to wait till mid-September.

A previous delay for the verdict was announced in July, when Mr Pickles' family were told that the case would have to be referred back to the High Court in Bangkok.

Reacting to the latest setback, Mrs Pickles said: "We feel frustrated and angry that this could have happened. It's gone on for so long, and it's like an emotional rollercoaster. We put our faith in the Thai justice system, but we're very unsure about what's going to happen and unsure about when we're going to see justice for Adam."

Andrew Pickles said the family's dealings with the Thai justice system had been complicated by the language barrier, and by the different legal procedures followed in Thailand.

He and Mrs Pickles said they had received very little support from the British Government, though were hopeful that this would change.

Married father-of-one Adam Pickles, who had been teaching English in Thailand, was flown back to the UK and spent six months at the Royal Hospital for Neurodisability in London before being transferred to Woodlands Respite Care Centre in York, close to his parents’ home in Thorner.

He is 41-years-old, and a former Bradford Grammar School pupil. Fundraising is continuing to help pay for legal costs and Mr Pickles’ care.

His mother said he was no longer classed as being in a "deep coma". "We're getting responses from him, he can say names, smile and indicate that he can hear," she added.
