A motorcyclist seriously injured in a crash is searching for the man and female doctor who saved his life a decade ago.

Andrew Mackay, 35, from Morden, broke two vertebrae and smashed seven ribs in a motorcycle accident at a roundabout on Horton Lane by Horton Country Park in July 2005.

A man, who lived next to the roundabout, heard the crash and rushed to help with his friend, a doctor.

Together they stopped him from choking on his own blood after one of his ribs punctured a lung and tended him until an ambulance arrived.

It took seven months before Mr Mackay recovered and when he did he tried find the pair to thank them.

But he had no luck and now, a decade later, has just launched an appeal on social media to track them down.

He said: "It’s something I have always wanted to do, and 10 years on I thought why not try. It’s to find them and thank them. It’s my own quest as it were."

Carpenter and builder Mr Mackay said his motorbike breaks did not work properly and he crashed into the roundabout on July 5.

To this day, he still has aches and pains due to problems with his rib cage and kidneys. He said: "I think my body was back in one piece within seven months, but it took a long time for me to recover properly."

Last night Mr Mackay posted on Facebook: "Did you save my life in Epsom/Chessington in July 2005? Please share this post to help me find the people who saved my life.

"The accident left me with several injuries, the most life threatening at the time however was one of my ribs puncturing my right lung causing me to be unable to breath properly.

"I was lucky enough to have had a man who lived next to the scene of the accident to hear the crash and was quick enough to act in driving to the house of a friend who lived down the road to get help, this friend was a female doctor.

"She saved my life at the side of the road by managing to deflate my lung stopping me from choking on the blood that was filling my lung up."

After Mr Mackay recovered, he went to find the man to thank him only to find that he had moved. There was no record of the name the doctor gave to the ambulance crew.

He posted: "I have always wanted to find this man and the doctor to thank them both, and I am hoping that with the help of modern social media I will be able to do so.

"If you lived in the area back in 2005, or know anyone that did please share this post for me so that one day someone may know who they were."

Of the crash itself, Mr MacKay told this newspaper: "It was a mixture of mechanical failure and driver error. The brakes decided to play up and not work properly. That caused me to panic that caused rider error."

As advice to other motorcycle riders, Mr Mackay said: "Don’t let just anyone work on your bike. Either do it yourself or find somebody that you trust.

"If I had, maybe I wouldn’t have gone through what I went through."

Mr Mackay got back on his motorcyle as soon as he could and alongside his day job he fits motorcycle ground anchors to keep other people’s bikes secure.

Do you know the man and female doctor who helped him?
