An investigation into Luke Graham was opened when evidence of a criminal conviction for the attempted importation of anabolic agents, including testosterone, nandrolone, and trenbolone, was passed to UKAD from the Courts of Guernsey.

Graham, who is from the island, admitted the attempted use of a prohibited substance and, as the violation was committed in June 2014, a sanction of two years was imposed.

The boxer is banned from all sport from June 1, 2016 to May 31, 2018.

"This case is a good result for UK Anti-Doping," said Pat Myhill, UKAD’s director of operations.

"It serves to highlight that a robust anti-doping programme is not built solely on testing athletes.

"A key part of our programme is the use of intelligence and information from a wide range of sources and developing relationships with local law enforcement and other partners.

"Information related to doping activity - however small - can make a difference in our fight to protect clean sport.

"We encourage anyone with information relating to doping, to report it via 08000 322332 or reportdoping.com."

UKAD has come under fire itself recently, being strongly criticised in an independent report this month for its failure to alert the General Medical Council (GMC) about allegations that a Harley Street doctor had helped sportspeople take performance enhancing drugs.

Last month, British world heavyweight champion Tyson Fury denied claims of taking performance enhancing drugs after it was claimed the boxer was being investigated by UKAD. 

According to the Sunday Mirror, the 27-year-old was found to have had "unacceptable" levels of the banned anabolic steroid nandrolone in a sample ahead of his world title fight with Ukraine’s Wladimir Klitschko last year.

Fury was told by UKAD officials in September that the levels of the steroid had been higher than would normally be produced by the body naturally.

It was also claimed that his cousin Hughie, also a heavyweight boxer, had been above the normal natural limit as well. 

Nandrolone has been known to help to increase muscle size, strength and power.

Both boxers are reportedly set to be brought before an independent panel to explain the levels of the substance found, however they have denied the allegations against them.
