The Hungarian Athletics Federation (MASZ) have revealed that the London 2012 gold medalist tested positive following analysis of a sample taken on January 13 in his hope city of Szombathely.

He failed for what was adjudged to be a "non-performance-enhancing" substance - meaning that he received a reduced punishment.

The actual identity of this substance has not been announced, however, although it was claimed it is only forbidden during competition periods.

Pars said in a statement posted on the governing body website that he is "indescribably ashamed" about the incident.

He blamed it on a "a bad decision made during a very difficult time in my career and life".

"I have to apologise to my family, my coach and everyone who has been with me over the years," he added.

"As an athlete under the forced rest of one-and-a-half years of waiting for me, I feel like I'm obliged to clear this gap and show me what I'm still capable of. 

"I want to do all this by avoiding publicity, I ask the media representatives to do this to me,"
