Gold Coast Titans chief executive David May says police have no interest in a five-year-old jam jar, believed to be filled with urine, that was found at the NRL club's home ground.

May found his club under scrutiny on Friday after News Ltd reported that police had found vials of urine hidden in changing room plumbing at Skilled Park.

That scrutiny was heightened because the report coincided with the Australian Crime Commission's damaging revelations about doping and crime links in Australian sport.

May said early on Friday he understood a single vial had been found and passed on to the Australian Sports Anti-Doping Authority (SADA) and pointed out that the Titans weren't the only team to use Skilled Park.

Later he effectively declared it a non story.

"Police have confirmed that it's not a matter they'll be taking any further," May said.

"We've had it confirmed that the vial of liquid found was not a vial, but a jam jar.

"We believed the liquid is urine, but we're not sure.

"The jar is around five years old and there's 100s of teams that have been through our change rooms in that time.

"...The finger has been pointed at the Titans because it's convenient to do so. There is no connection between the sample and the club."
