Indian team officials were also warned about the use of needles and their correct disposal after syringes were found where their wrestlers and a para-athlete was staying in Glasgow.
Commonwealth Games bosses have promised that cheaters will be caught as they continue to investigate the discovery of needles at Gold Coast's athletes' village.
The team is mainly composed of newcomers, especially athletics, and that presents a good opportunity for the coaches to gauge our sportsmen and women whom they are grooming for the 2020 Tokyo Olympic Games.
"The syringes were not found in Indian athletes' rooms".
The storage will mean samples can be re-tested at a later date and if an athlete is found to have used a banned substance they could be stripped of medals, as has happened to Olympic athletes.
Grevemberg said reports Indian athletes had been placed on a curfew was news to him and as far as he was aware the curfew hadn't been imposed by the CGF.
And it is the Indian contingent that is in the eye of the storm despite protestations by senior officials that all are clean and no one is involved in the alleged doping attempt.
"The draw is quite tough especially with the presence of a few top ranked pairs from India and England, so we have to give more attention to these two pairs and not to take them lightly". It's unfair that we are being doubted. It's a norm that randomly many athletes are tested before the Games begin. "Because the measures that have come in for drug-testing means these will be the cleanest Games, they'll be friendly Games and at the end of it our reputation globally will be restored", he explained.
The Commonwealth Games has a "no-needles" policy for athletes, and Commonwealth Games Federation (CGF) chief executive David Grevemberg said "if analytical evidence indicates it's worth a follow-up, the CGF medical commission will follow procedures".
