At least seven undocumented farmworkers were arrested by federal authorities while they were working Wednesday morning outside Yakima, according to an immigrant support group.Danielle Surkatty, a volunteer with the Yakima Immigrant Response Network, said Thursday morning that YIRN volunteers confirmed seven people were arrested by federal officers while they were working in the Naches Heights area.YIRN confirmed the arrests, which took place from approximately 5 to 7 a.m. Wednesday, with information from family members and detention records from the Northwest ICE Processing Center in Tacoma. YIRN was told eight people were arrested, but ICE detention information hadn't yet shown up Thursday for one person, Surkatty said. The Herald-Republic hasn't independently verified the detentions, which requires personal information."The families all attest that they were there," she said.Family members told YIRN federal authorities lined up the people they saw in the orchard, handcuffed them and questioned them about their status. Those arrested were not farmworkers with H-2A visas, which allow them to be in the United States as temporary foreign labor.Orchard company: Our employees weren't arrestedLaw enforcement officers asked to come on Evans Fruit property Wednesday as they were chasing a fugitive, said Kim Hiebert, vice president at Evans Fruit. The person they were chasing — who was not an Evans Fruit employee — was arrested, she said."We have been told by law enforcement that they were chasing a fugitive, and they had warrants for his arrest," she said. "He is not one of our employees. He turned onto one of our ranches in the Naches Heights area, and he was detained."If anyone else was arrested, it was not on Evans Fruit property, she said."None of our pickers were arrested yesterday. We have a full crew working today (Thursday)," she said.Hiebert was not sure which agency was involved, and did not believe it was a sheriff's deputy or local police officers.She "asked our ranch manager specifically if it was ICE, and the ranch manager said no."A video shared by a YIRN volunteer shows a masked officer in an orchard saying, "we weren't trying to do a raid or anything."The Yakima Herald-Republic and El Sol de Yakima have reached out to ICE and U.S. Customs and Border Protection for comment.An ICE spokesperson previously has told the Yakima Herald-Republic in a statement that ICE uses "reasonable suspicion" to investigate immigration status and probable cause to make arrests consistent with Title 8 of the United States Code and the Fourth Amendment to the U.S. Constitution.Immigration enforcement has picked up in Yakima County over the past few months.Nearly 445 ICE arrests were made in Yakima County between March 11 and Aug. 5, the vast majority of them in Yakima. The arrests accounted for about 17% of the statewide total, and almost 70% didn’t involve people with pending charges or criminal convictions, according to processed by the Deportation Data Project and analyzed by the Yakima Herald-Republic.The city of Yakima alone saw just over 400 arrests, the highest in the state.YIRN volunteers on Wednesday gathered information from relatives of the men arrested, confirmed who was detained and met with families, Surkatty said. YIRN deposited funds in the commissary accounts of those detained, for calls to family and other necessities.That work continued Thursday. And the Northwest Immigrant Rights Project has pledged "to provide initial legal counsel to all these men," she said. That usually involves a wait of four to six weeks, but "they said they would try to fast-track these men because it was classified as a raid." This story is developing and may be updated.
