CARIBOU -- A 28-year-old New York woman broke her ankle in an all-terrain vehicle accident at about noon today in the Caribou area.

Nicole Pone, of Albany, N.Y., was riding with two others on three ATVs on the multi-use trail from Caribou to New Sweden when she hit a mud puddle and flipped her vehicle at least twice, according to Game Warden Ed Christie of the Maine Warden Service.

Christie said Pone suffered a broken right ankle, a serious injury that could require surgery. Pone was not wearing a helmet, he said.
