New Delhi: Boxing icon Vijender Singh, accused of using heroin, submitted blood and urine samples today to the National Anti-Doping Agency or NADA.
However, the blood and urine tests may not help ascertain if the boxer consumed heroine. The drug does not last for more than 12 hours in blood and three days in urine. Only a hair sample of Vijender's can now prove whether he took heroin or not, since traces of the drug can be found in hair for upto three months. NADA says they do not have the facility to test hair samples.
Meanwhile, Vijender's close friend and sparring partner Ram Singh was arrested by the Punjab Police today.
