The last occupier of the Oregon wildlife refuge says he turned himself in to authorities a couple of hours after three others walked out.

The surrender played out over a phone call on an open line streamed live on the Internet by an acquaintance of occupier David Fry. Fry, who shouted and rambled, had delayed leaving Malheur National Wildlife Refuge after he said the other three surrendered.

Fry said, "I'm walking toward them (FBI agents) right now" during the call with his acquaintance and a Nevada legislator who drove to the site to help negotiate the group's exit.

Rep. Judy Boyle, an Idaho state lawmaker, confirms that the four holdouts are in custody.

They were the last remnants of armed group that seized the refuge on Jan. 2 to oppose federal land use policies.

Meanwhile, federal prosecutors in Las Vegas are charging Cliven Bundy with conspiracy, assault on a federal officer, obstruction, weapon and other crimes.

A criminal complaint filed Thursday stems from Bundy's role at the center of a tense April 2014 armed standoff with federal officials near his ranch in Nevada.

It involved self-styled Bundy militia supporters pointing military-style weapons at federal agents trying to enforce a court order to round up Bundy cattle from federal rangeland near his ranch.

Bundy was arrested Wednesday night when he arrived at Portland International Airport from Las Vegas.

He's being held at the Multnomah County Jail pending an appearance in federal court. It wasn't immediately clear if he had a lawyer to represent him.

He is the father of the jailed leader of a group that occupied an Oregon federal wildlife refuge.
