Nineteen year old Darren Wyllie from Dalkeith in Scotland has been informed ny doctors that he may have been left disabled after suffering a broken leg in a motorbike crash.

Mr Wyllie claims a motor bike sped towards him as he crossed the town's South Road last Friday night. He was knocked out and a witness of the accident asserted that the rider of the Suzuki motor bike stopped a short distance up the road to look back, before accelerating away.

Darren has now been told there is a high chance that he will not be able to return to his job as a steeplejack, and may be left with a permanent limp. He said: "The road was very busy with cars and I saw the motorbike coming towards me, but it was slowing down so I thought I could make it across but at the last minute it started coming up really fast and hit me. "I reckon it was doing between 30-40mph when it hit. The front wheel hit my right knee and I got spun round and hit the back of my head on the road. "I can't remember anything until I came round in the hospital about an hour later, but I was told that I had my eyes open after about five minutes but was just staring into the sky."

The teenager had spent the evening in the local snooker club with his mum Val, 42, and friend Lewis Carr, 19, also of Dalkeith. The party emerged about 11pm and Lewis and Darren decided to go on to a friend's house nearby. Lewis said that the motorcyclist sped up before hitting his friend and only stopped for the briefest of moments. He added: "I don't know what he was playing at. He could have stopped in time but he chose not to."

An ambulance arrived shortly after and took Darren to Edinburgh Royal Infirmary where they confirmed that his leg was broken. Doctors said there was less than a 50-50 chance that he would be able to return to work.Darren said: "My work involves a lot of climbing on roofs and up scaffolding to fix church chimneys and the like, and it also involves a lot of rope work and abseiling. "Obviously, I can't do that with a broken leg and the doctors won't know if it will ever heal back in place for another six months. "I may be left with a permanent limp after this and if that's the case it will affect my social life too, so obviously I'm pretty gutted."

Police called the incident "a deliberate and calculated act" and are appealing for witnesses. A spokeswoman added: "Although the injuries were not life threatening the victim will require a significant period of recovery."There were a number of people in the area at the time and we would like to hear from anyone who may have witnessed the incident or who may have any information relating to this crime."
