A Santa Rosa man suspected of threatening people with a knife at a Russian River campground and then fleeing from deputies was in custody Tuesday.

Deputies arrested Dale Bohan, 39, late Tuesday morning as he waited in Guerneville for a bus, Sonoma County sheriff's Lt. Steve Brown said.

Bohan also was being investigated as a possible suspect in a second incident, a knife assault on a woman at about 2 a.m. Tuesday in Guerneville, Brown said.

Witnesses told deputies that Bohan pulled a knife on them at about 8 p.m. Monday at the Faerie Ring Campground on Armstrong Woods Road, said Brown.

Deputies were called to the campground by two women who said a man, possibly under the influence of drugs, had demanded sex from them and become very aggressive when they turned him down.

When others tried to intervene, the man threatened them with the knife, witnesses said.

A deputy arriving to the call saw a man matching the description driving on Highway 116 at Fourth Street in a red Toyota T-100 pickup. The truck had been stolen several hours earlier, Brown said.

The driver sped away from the deputy, leading to a 1?-mile pursuit on Highway 116. Near Riverside Drive, the driver lost control and the pickup flipped and crashed.

The driver ran from the truck toward the river and disappeared. A search by deputies, the CHP, a CHP helicopter crew and police dogs was unsuccessful.

At about 11 a.m. Tuesday, witnesses from the campground incident spotted Bohan and called deputies.

Bohan was carrying a knife and a wallet, which had come from the stolen pickup, Brown said.

Bohan, who had an injured hand and facial injuries, was arrested on suspicion of evading arrest, possession of stolen property, making terrorist threats, vehicle theft, resisting arrest and a no-bail parole hold.

He was taken to a hospital for a medical evaluation before going to the Sonoma County Jail.

Meanwhile, deputies were investigating a report of a 2 a.m. attack on a woman walking on Old River Road.

The woman said a man with a knife jumped from bushes and slashed at her. She had a superficial stomach wound, Brown said.

The woman said she punched the man in the face, they both fell and he ran.
