The 41-day standoff at an Oregon wildlife refuge took a dramatic turn Thursday when three of the four remaining occupiers surrendered, according to David Fry, the last occupier. Fry, speaking on a live streamed phone call, said he was the last holdout.

Fry abruptly decided against coming out of the federal Malheur Wildlife Refuge's headquarters in Harney County, Oregon, and contended that his grievances have not been addressed, according to the audio stream on YouTube.

His decision came after the armed occupiers indicated they would turn themselves in Thursday morning, hours after federal agents arrested Cliven Bundy, the father of protest leader Ammon Bundy.

Ammon Bundy has already been arrested in the standoff.

A Facebook page for Cliven Bundy's ranch announced that Bundy -- who came to the national spotlight in a fight with the federal Bureau of Land Management over grazing rights for his cattle in 2014 -- was heading to Oregon earlier Wednesday.

"It's time," the post said. "Cliven Bundy is headed to the Harney County Resource Center in Burns Oregon."

Bundy was taken into federal custody in Portland, Oregon, after landing there early Thursday morning, the FBI said.
