Police are investigating the death of former NASCAR driver Kevin Grubb, after the 31-year-old's body was discovered in a motel room in Henrico County.

Personnel at the Alpine Motel found Grubb in his room at around 11am on Wednesday, with officials stating that there didn't appear to be anything unusual or suspicious at the scene.

Grubb, who made over 170 starts in the Nationwide Series between 1997 and 2006, had been suspended by NASCAR on two occasions for substance abuse; the first suspension coming in 2004 when he failed a drugs test.

Having agreed to undergo random checks, Grubb was reinstated into the sport before being suspended indefinitely in September 2006 when he refused to take part in a random test at Richmond.

Grubb made one unsuccessful attempt to qualify for a Sprint Cup race in 2002, but failed to qualify the #54 Team Bristol Motorsports Chevrolet for the Pontiac Excitement 400 at Richmond.

More details surrounding his death are set to be revealed today [Thursday].
