The daughter of a man who was badly injured when a car ran him off the road in a hit and run has appealed for help.

Patrick Kelly was cycling along Claremont Avenue in Motspur Park just after 8am on February 25 when all of a sudden he came face to face with a turning car.

His daughter, Caroline Kelly, said the car was driving so fast that her father had no chance to get out of the way.

"The windscreen was smashed from the impact of my dad hitting it," she told the Wimbledon Guardian.

"Although he's 75, he's amazingly fit and strong, rides his bike everywhere, tends his garden in New Malden, and an allotment in Morden."

But that lively man will be stuck recovering for the next six months.

"At this stage, the extent of his mobility is that he can shuffle very short distances, using an upright frame," Caroline added.

"You can only imagine how frustrating this is for him.

"He's in a lot of pain which the excellent team at St George's are working hard to manage whilst also promoting his mobility.

"He is going to require round the clock support when he returns home which is going to be hard on my mother who is also in her seventies."

She said the driver who hit her dad initially stuck around, but drove off once he heard police were on their way.

Now she is appealing to the public for help in tracking down the driver.

"The car was an old small silver car, sized similar to a VW Polo," Caroline said.

"The driver was a white male, 55-60 years, wearing scruffy clothes including jogging bottoms and a body warmer.

"He had white thinning hair, wore a beanie hat, and had a dark beard with substantial white hair through it.

"We know that he drove down to the roundabout on Burlington Road and drove towards Shannon Corner."

She has implored anyone who may have captured anything on CCTV to get in touch with the police on 101.
