PHILADELPHIA — ICE agents have arrested nearly 20 immigrants in Norristown, Pa., during the last two weeks, according to advocates who described an aggressive and ongoing enforcement campaign in the seat of Montgomery County.

“Every day, every day,” said Denisse Agurto, executive director of Unides Para Servir Norristown. “As many as nine cars, and more Spanish-speaking officers — people who look like us and talk like us.”

The arrests in the suburban municipality, where one in three residents is Latino, come as President Donald Trump named Montgomery County to a list of so-called sanctuary jurisdictions from which he has threatened to cut federal funding.

Agurto’s organization contacted the Norristown Municipal Council for help, and families plan to address the Montgomery County commissioners on Thursday to ask that a newly hired immigration-affairs director become an active voice of support for undocumented people.

ICE officials in Philadelphia, headquarters for operations in three states including Pennsylvania, did not respond to requests for comment about the arrests.

William McCoy, a borough council member, called the situation “heartbreaking and unacceptable.”

“Families are being torn apart. Fathers are being taken from their children. People who have built their lives here, who contribute to our community every single day, are living in fear,” he said in a statement. “This is not justice. This is cruelty.”

Council member Mydera Robinson also spoke out, telling families: “You are not invisible. You are not alone.”

“We are a community, and we must recognize that what impacts one of us, impacts all of us,” she said. “We are stronger together.”
