Ram, a super heavyweight boxer who was Vijender's roommate in the National Institute of Sports in Patiala, said he and Vijender "consumed small quantities of drug" on a few occasions.
It was given to them by NRI Anup Singh Kahlon, the key accused in the Rs 130 crore heroin haul case, who attempted suicide in police custody yesterday.
"Me and Vijender experimented with drugs thinking that they were food supplements. We did not know that we were taking drugs. We were told that we were consuming food supplement meant to increase strength and stamina," Ram told reporters after being questioned by the police in Fatehgarh Sahib.
Earlier, sources in the Punjab Police said that Ram had told the police during his questioning that former world number one Vijender, who is currently employed as DSP with the Haryana Police, and had consumed 1-3 grams of heroin given to them by Kahlon.
The sources said that Ram Singh had told them that he had met Kahlon in the past but claimed ignorance about his criminal connections.
