DAD Jason Edwards, who was left in a coma for nine weeks after suffering severe head injuries in an incident in Devizes, is upset that no serious charges are to be brought.

He was told by police on Tuesday that a man and a woman, who have been on police bail, since Mr Edwards was found slumped in the doorway of Boots in The Brittox on September 29, would not be charged.

He was told a second woman is to face a minor assault charge.

His partner, Hazel McCarthy, is now writing to Prime Minister David Cameron and the couple are filling in a Crown Prosecution Service victim complaint form.

Mr Edwards, 42, said on Wednesday: "I find this very distressing. I am still suffering from my injuries and have a big hole in the front of my head. I still have a black eye and the left side of my body is weak.

"It has been a terrible ordeal for my whole family including Hazel and my two sons. My mum broke down in tears when I told her there would be no major charges."

In a phone call from police Mr Edwards, who works as a driver, was told that it had been decided the blows he suffered were in self-defence. He hit his head on a bin as he fell to the ground and is unable to remember anything about the incident.

He said: "I had been in the Corn Exchange but I had only had a couple of beers as I was working the next day. I started to walk down The Brittox and I was on my mobile to Hazel to ask her to come and collect me."

He said he did not know the three people who were arrested but he has been told by police something was said between him and one of the women and it is alleged he hit her. One of the people she was with then allegedly retaliated.

Mr Edwards, who has two sons Jarod, 16, and Jack, 11, spent months in Southmead Hospital and later Royal United Hospital, Bath, until he was released on December 10.

Ms McCarthy said: "He was on the phone to me and I heard something happening. When I arrived in The Brittox he was unconscious and I helped give CPR until the paramedics arrived.

"When he was in hospital it was terrible. A couple of weeks in when he was still in a coma we were told we might have to make difficult decisions."

She played music from Kasabian and Randy Crawford to try and bring him out of his coma.

She said: "This has changed all of our lives."

A force spokesman said: "Wiltshire Police have completed an extensive and comprehensive investigation in relation to this case, and as a result, three people were arrested.

"The evidence was passed to the Crown Prosecution Service to make a charging decision in relation to the three arrests. Subsequently, they have decided to charge one female with assault.

"As a victim of crime, Wiltshire Police have supported Mr Edwards through this difficult time and will continue to do so."
