Oregon Revised Statutes Procedure in Criminal Matters Generally § 144.331

(1) The State Board of Parole and Post-Prison Supervision may suspend the parole or post-prison supervision of any person under its jurisdiction upon being informed and having reasonable grounds to believe that the person has violated the conditions of parole or post-prison supervision and may order the arrest and detention of such person. The written order of the board is sufficient warrant for any law enforcement officer to take into custody such person. A sheriff, municipal police officer, constable, parole and probation officer, prison official or other peace officer shall execute the order.

(2) The board or its designated representative may proceed to hearing as provided in ORS 144.343 without first suspending the parole or post-prison supervision or ordering the arrest and detention of any person under its jurisdiction upon being informed and having reasonable grounds to believe that the person under its jurisdiction has violated a condition of parole and that revocation of parole may be warranted or that the person under its jurisdiction has violated a condition of post-prison supervision and that incarceration for the violation may be warranted.

(3) During the pendency of any post-prison supervision violation proceedings, the period of post-prison supervision is stayed and the board has jurisdiction over the offender until the proceedings are resolved.
