RENO, Nev. (AP) — Animal rights activists say additional videotape shot at the Reno Rodeo shows the alleged abuse of bucking broncos was more extensive than originally thought.

Leaders of Showing Animals Respect and Kindness, or SHARK, publicized videotape last week they say showed an unknown person secretly giving electric shocks to horses just before they left chutes for competition last month in violation of the rodeo’s policy.
