Actor Vinnie Jones is demanding the prize money his greyhound won at the world's richest race - even though the dog proved positive for an illegal substance. The Gone in 60 Seconds actor is taking the Irish Coursing Club to the High Court to recoup the 80,000 Euro ($63,700/GBP33,500) prize, claiming the decision to strip him of the money is illegal. The greyhound named BOAVISTA won the Irish Cup earlier this year (06) but was later disqualified after testing positive for a prohibited substance. A source close to Jones tells Irish newspaper the Sunday World, "We were never given any statements by witnesses who compiled the drugs test evidence. "We were therefore never furnished with a proper chain of evidence in relation to the alleged positive test on Boavista."
