Police said Singh bought drug along with his friend and fellow boxer Ram Singh from the dealer. They had purchased drugs from December to February this year, police said.
The duo had gone to the house of arrested drug dealer Anoop Singh Kahlon, said police.
"As per investigation conducted so far, Vijender Singh consumed the drug about 12 times and Ram Singh about five times," a Punjab Police statement said.
Police said Vijender knew Kahlon and there were several SMS exchanges. About 80 times they spoke to each other too.
Police said since they did not actively connive with the smugglers in their activities and nothing was recovered from them there are no arrests at the moment.
Earlier this month Vijender Singh was interrogated for hours by the Punjab Police. Singh had refused to provide his blood or hair samples for forensic examination to ascertain if he had taken drugs or kept links with the arrested NRI drug dealer.
Vijender had earlier admitted that he had met the accused Anoop Singh Kahlon once through Ram but had maintained that he did not know him personally. Kahlon has claimed close links with Vijender and Ram.
Police had raided the flat of the peddler in Zirakpur and recovered 26 kg of heroin worth Rs 130 crore. Vijender's name cropped up also because his wife's car was found parked outside the building that housed the flat.
Ram Singh was expelled by the National Institute of Sports in Patiala after he admitted to taking drugs in this case.
