Friends and relatives of a man who died in the terrorist attacks in America have bought a horse in his honour.

Bookie William Hill has lent its support by pledging to bet £100 on the horse every time it races.

All winnings will go to charities nominated by the family of horse racing fan Geoff Campbell, 31.

Geoff, who worked as a risk analyst for news agency Reuters, was on the 106th floor of the World Trade Centre's North Tower when the suicide attacks began.

His body has still not been recovered.

His brother Matt, 32, and younger brother Rob have invited their family and Geoff's friends to buy a part-share of a racehorse.

The family, all horse racing fans, say their horse will be called Geoffster, the nickname they used for Geoff.

Matt, of Woodsland Avenue, Hassocks, said: "The family is delighted that William Hill has offered to place bets on our horse.

"I used to work for William Hill in Northampton.

"It was only a student job but it was the start of our family's interest in horse racing.

"One of my first bets was on a 33-1 shot and it came in. It was such a thrill. I hope Geoffster can win a few races with odds like that."

He said 35 people had so far pledged £250 each for a share of the horse and they were being advised on what to buy.

The horse would be raced over the flat, he added, because there was less chance of injury.

A spokesman for William Hill said: "All the winnings from the horse will go to charities nominated by the family.

"Even if it loses, we will give £100 to those charities."

Geoff Campbell used to visit the UK three or four times a year.

He had lived in New York for two years and was engaged to Caroline, an American.

Clearing the remains of the World Trade Centre is expected to take at least a year.
