The suit against the Attorney General of Canada and 13 others says Staff Sgt. Caroline Mary Sarah O'Farrell, 52, was subjected to abuse while a constable in the Musical Ride, the police force's travelling equestrian show.
The statement of claim alleges O'Farrell, the only woman in the Musical Ride, was subjected to a disciplinary procedure in which she was doused with water and dragged through stall shavings mixed with horse manure and urine because she was a woman. It also says she was harassed by her attackers when she asserted herself.
A RCMP investigation substantiated more than 100 incidents of harassment, but only token disciplinary action was taken, her claim states.
O'Farrell is currently assigned to an RCMP office in Ottawa, the Canadian Broadcasting Corp. reported Tuesday.
