(Portland, OR) -- A 28-year-old Portland woman faces a federal charge for allegedly assaulting an officer outside of the ICE building. Twenty-eight-year-old Lucy Shepherd was arrested Friday outside Portland's ICE building after authorities say she hit an agent's arm. Prosecutors say the altercation happened when federal officers were clearing the driveway so vehicles could exit. Following the court hearing, Shepherd was released, pending further proceedings. She is the 38th person charged with federal crimes outside the facility since protests began in mid-June.
