Police say a Twin Falls County Sheriff’s deputy has been arrested and arraigned on three counts of domestic battery inflicting traumatic injury.  The 15 year veteran of the sheriff’s dept. was identified as Sgt. Michael Cooper.  Police say a woman told them she had been subjected to domestic abuse by Cooper on several occasions starting in 2008.  At his arraignment on Wednesday, prosecutors asked for a $500,000 bond for Cooper citing a concern for the protection of society and alleged victims.  After consideration Magistrate Judge Tom Kershaw set Cooper’s bond at $100,000, and Cooper bonded out after the hearing.  But as soon as Cooper posted bond in Twin Falls County the Times News reports he was re-arrested on a warrant for a charge of domestic violence with traumatic injury in Camas County against the same woman.  His arraignment on the Camas County charge will take place in Twin Falls County today.  A preliminary hearing for the Twin Falls County charges is set for next Friday.  Cooper faces ten years in prison on each charge including a $10,000 fine.
