PORTLAND, Ore. (KATU) — Police detained one person Friday night not far from the Immigration and Customs Enforcement facility in South Portland in a “targeted arrest” during a May Day protest.It was not immediately clear what prompted the arrest outside of Gray’s Landing on Southwest Bancroft Street and Moody Avenue, which is across the street from the facility, but the Portland Police Bureau posted on X that officers had observed "criminal activity."Protesters surrounded police officers as they detained the person.Protesters took part in May Day rallies Friday in Portland, gathering in the South Park Blocks and Elizabeth Caruthers Park.Protesters rallied at the Elizabeth Caruthers on Friday evening and then marched to the ICE facility.Some people dressed in all Black chanted, “Death, Death to the DHS.”At the facility, protesters approached its gate chanting, "Revoke the permit."Over a loudspeaker, the Department of Homeland Security ordered protesters to get off federal property.As hundreds of protesters pressed toward the facility, a Portland police vehicle arrived with police officers in riot gear standing on its running boards. The officers stepped off the vehicle and immediately pressed through the protesters to take up a position in front of the ICE facility's gate, keeping the protesters away from the building.Officers on bikes also arrived to bolster the police line.Later Friday, night Portland Police gave more details on the arrests.In a detailed account of the day’s events, the Portland Police Bureau said it activated an Incident Management Team to monitor a “large-scale free speech gathering and march in honor of May Day.”Before that activation, officers responded to a hotel in the 1300 block of Southwest 2nd Avenue and found a sit-in demonstration in the lobby, police said. Eight people were sitting on the floor holding signs and chanting, and more than a dozen others were there to support them but left willingly, according to police. The eight were arrested without incident for second-degree criminal trespass, police said: Hana Francis, 26, of Portland; Leila Achtoun, 27, of Ukiah, California; Lucy Breuer, 29, of Portland; Casadie Kimball, 32, of Portland; Sarah Eichstadt, 33, of Portland; Abraham Ornie, 34, of Portland; Lara Dunn, 37, of Milwaukie, Oregon; and Sophie Rittenbaum, 25, of Portland.Police said Patrick Eckburg, 28, of Portland, was also arrested at the hotel and charged with second-degree disorderly conduct, interfering with public transportation and fourth-degree assault.At about 1:30 p.m., as a large crowd gathered in the South Park Blocks, officers witnessed a protest-related assault near Southwest 10th Avenue and Southwest Jefferson Street and arrested Marissa Arredondo, 37, of Salem, Oregon, police said. She was charged with harassment and second-degree disorderly conduct, according to police.Police said that at about 3:15 p.m., demonstrators began marching from the South Park Blocks, and the march was peaceful and concluded around 5 p.m.After the downtown events, police said a second Incident Management Team was activated to monitor protest activity in the South Portland neighborhood near the ICE building, with resources that included the Rapid Response Team, Mobile Field Forces, a sound truck, air support and dialogue liaison officers. Police said they were assisted by Oregon State Police and Portland Fire & Rescue.Early in the evening, police said officers observed two suspects they had probable cause to arrest from previous criminal activity. Michael Duntley, 58, of Portland, was arrested and charged with reckless endangering, second-degree criminal mischief and second-degree disorderly conduct, police said. Jaelynn Hemsley, 29, of Portland, was arrested and charged with third-degree criminal mischief, according to police.At around 8:30 p.m., police said officers observed criminal behavior and made targeted arrests. Cole Dunahugh, 22, of Beaverton, Oregon, was arrested and charged with second-degree trespass, police said. Catherine Esperanza, 30, of Baltimore, Maryland, was arrested and charged with interfering with a peace officer and resisting arrest, according to police. Payton Reed, 22, of Eugene, Oregon, was arrested and charged with harassment, police said.Police said that at times during the evening, members of the crowd threw rocks and water bottles at officers. One officer suffered a non-life-threatening injury from a large rock and was taken to a local hospital, police said. Another officer was injured and evaluated at the scene, according to police.Since June 2025, police said, the total number of arrests related to ICE protest activity, including Friday night, is 94. Friday's march to the ICE facility came a few days after a federal court of appeals ruled in favor of the Trump administration, saying federal officers can use tear gas and chemical munitions on protesters outside the ICE facility in South Portland.The plaintiffs argued that the gas drifted into their units and caused them health problems.Mercedes Moreno lives at Gray’s Landing and is a plaintiff in the lawsuit.She came outside on Friday night to see if the authorities used tear gas on the protesters. If they did, that would be the signal for her to close her windows in her apartment.“I usually have my bathroom ready to go, towels by the door. ... I have my little strategy -- grab my tear gas wipes that I have in my bathroom, and just get ready with my cat. My cat is pretty well trained at this point. He just kind of runs in there when it starts coming.”She said if it gets too crazy, she would get a hotel room.KATU's Jennifer Singh contributed reporting.
