A champion Irish greyhound has tested positive for a cocaine-like drug.

Clonbrien Hero, winner of the prestigious Laurels race, showed traces of benzoylecgonine in three samples.

The dog - which is trained by Graham Holland - tested positive for the prohibited substance in July.

The Irish Greyhound Board has released a statement in response to the allegations this morning - but says it can't comment on individual cases.

The board says the findings "have been referred to the Control Committee and which may proceed to investigation".
