The British Horse Authority has now turned its attentions to the stables of Saeed Bin Suroor's Stanley House in Newmarket, this move comes following the doping crisis that has rocked Godolphin, according to the Racing Post.
Horses have already been sampled at former trainer Mahmood Al Zarooni's stable at Moulton Paddocks. Sampling results are expected into a few weeks, while interviews with staff are continuing.
The BHA confirmed on Thursday that the whole Godolphin operation was to be investigated.
BHA spokesman, Robin Mounsey, said on Thursday night: "We can confirm that, for the sake of completeness, we are conducting testing in training at the yard of Saeed Bin Suroor, although there was no reason to link the two yards because of the common ownership by Godolphin."
