Twenty one horses died triggering speculations of anabolic steroidsTwenty-one horses from a Venezuelan team competing at the US Open Polo Championship died after they all collapsed before a match in Florida.

Lechuza Caracas team veterinarian James Belden said it was unlikely that the horses had died due to a tainted medication or given anabolic steroids since they are banned in England where the team competes.

It is believed that the death of all horses could be possibly triggered by use of anabolic steroids.
