Commonwealth Games Gold Medallist Manju Wanniarachchi`s second urine sample had also tested positive for the banned substance Nandrolone, Sri Lanka Boxing Association confirmed today.

Wanniarachchi, who won gold in the 56 kg category at the Commonwealth Games, failed the first drug test during the Oct 3-14 Games held in New Delhi, India.

The Commonwealth Games Federation said Wanniarachchi`s `A` sample tested positive for the banned anabolic agent 19-Norandrosterone, a metabolite of nandrolone which is a prohibited anabolic agent under category S1 of the WADA list of prohibited substances and methods,`

Then they confirmed the result of the `B` sample on Friday.

According to regulations, Wanniarachchi will be suspended and stripped of his medal after the `B` sample also confirms the presence of a prohibited substance.

The boxer who won the gold medal in the 56 kg Bantam weight category at the 2010 Commonwealth Games in New Delhi tested positive for the performance-enhancing steroid nandrolone, in the `A Sample` test according to a report sent to Colombo by organisers of the New Delhi Games.

However Sri Lankan sports chiefs who had confiscated the gold medal won by boxer had stated that no action will be taken against Manju until the `B Sample` proves him guilty. They also gave him two weeks to answer to the doping charges.

It had been announced previously that the boxer will face a two-year ban and will be stripped of his medal if his `B Sample` test proves positive.

However, Wanniarachchi`s lawyer Kalinga Indratissa said yesterday in a statement that Sri Lanka will challenge the result as the drug test had allegedly not been carried out according to proper method.
