A 56-year-old man faces charges after authorities say he was spotted sexually abusing a horse in Grand Ronde.

According to a probable cause affidavit, the horse's owner and two other witnesses told a

that they spotted Glen A. Garbutt "masturbating himself and (the) horse," while on his property on June 4. It is not clear why the horse was on Garbutt's property.

The deputy searched for Garbutt but couldn't find him until June 28, when the deputy received a tip from a Grand Ronde Tribal police officer that the suspect was at a Seventh Day Adventist Church in Grand Ronde.

Garbutt ran when the deputy found him. The deputy repeatedly warned Garbutt that he would be Tased if he did not stop running. Garbutt was Tased at least three times before the deputy and other authorities who arrived as backup, were able to arrest him.

When the deputy told Garbutt he was being arrested on suspicion of sexual assault of an animal, the 56-year-old yelled that he didn't have sex with a horse, the affidavit said. At that point, the deputy had not mentioned anything about a horse.

Garbutt was booked into the Polk County Jail on charges of sexual assault of an animal, resisting arrest and interfering with a police officer.
