Banned bodybuilder Shaifulhaq Ahmad Ishak has had his two-year suspension from the sport restarted after he returned to competition prematurely following a positive result during an in-competition drugs test.

In June, Shaifulhaq flexed and posed his way to the middleweight title at the Singapore National Bodybuilding and Physique Sports Championship. But the 32-year-old won while still serving a two-year suspension for testing positive for drostanolone and methylhexaenamine at the 2012 national championship last August.

A panel comprising members of Singapore Sports Council's National Anti-Doping Advisory Board found Shaifulhaq guilty of violating the period of ineligibility and the bodybuilder will now see his ban restarted from June 29 this year, the date he took part in the championship at Singapore Expo.

The panel has also found the SBBF guilty of breaching the agreement to adopt, abide and implement the anti-doping rules by intentionally lifting the suspension to allow the athlete to compete.
