Suriname's top sprinter Issam Asinga has been handed a provisional suspension ahead of World Athletics Championship.
Athletics Integrity Unit (AIU) confirmed that the sprinter was suspended after being tested positive for doping.
"Asinga was suspended after his dope test traced presence or use of a prohibited substance, GW1516, with the World Championships set to begin on August 19," AIU stated.
The 18-years broke the under-20 record in the 100 metres when he clocked 9.89 seconds at the South American Championships last month, tying for the fourth fastest time of the year.
Asinga said the violation was related to an out-of-competition urine sample provided at home on July 18.
"I respect the AIU's processes, and I will continue to comply, as we work to find out what has happened," Asinga said in an Instagram post.
"My team and I are aware that the next generation of track stars is looking up to me, and I would never intentionally let them down."
