Commonwealth Games officials are investigating after needles and syringes were allegedly found at the Gold Coast athletes village.
This is a breach of the 'no needle' policy at the games, with the materials found over the weekend ahead of the Games, which begin on Wednesday.
Commonwealth Games Federation boss David Grevemberg has said that officials have been summoned to a meeting with the medical commission.
"This is very much an ongoing investigation but there has been a clear beach to the no-needle policy and the CGA has been summoned to meet with the medical commission," he said.
"These needles have been brought in and there was no approval for them to be there."
