JORDAN VALLEY, Ore. (AP) — An animal-rights activist has been arrested after refusing to quit videotaping at an Eastern Oregon rodeo with an event where contestants rope horses by the legs.

The Malheur County sheriff's office says 30-year-old Adam Fahnestock of Vancouver, Wash., was accused Saturday of disorderly conduct and resisting arrest. The group Showing Animals Kindness and Respect says he is a volunteer. Undersheriff Travis Johnson told the Ontario Argus Observer the Jordan Valley Big Loop Rodeo was on private property, so it could refuse to allow videotaping.

The rodeo in far southeast Oregon is the only one in the state known to hold an event that sponsors call horse roping and opponents call horse tripping. The Oregon Senate has voted to ban the event. The House is considering the bill.
