Bryony Frost ended what was an emotionally strenuous week in the best possible way when she delivered Greaneteen to an impressive win in the Grade 1 Tingle Creek Chase at Sandown on Saturday.Earlier last week, Frost had spent three days in front of a British Horseracing Authority (BHA) panel which heard charges of threatening and abusive behaviour towards her by fellow jockey Robbie Dunne, all but one of which he denies.
