Athletes or support staff taking part in the Enhanced Games would be in danger of committing anti-doping rules violations and should consider the serious health risks, the World Anti-Doping Agency (WADA) said on Wednesday.

Aron D'Souza, a London-based Australian entrepreneur, announced last month that he has attracted big-name investors, including Paypal co-founder Peter Thiel, to back his vision of an Enhanced Games where athletes, competing for themselves, are allowed to use pharmacological or technological assistance.
