A father and son have been arrested and separated by ICE agents during a routine immigration check-in in Lower Manhattan, according to multiple reports.

“We do not know where his six-year-old son is, and he has not been told where his six-year-old son is,” community advocate Jennie Spector said.

Reports say a Chinese asylum-seeker named Fei Zheng and his son, Yuanxin, arrived at 26 Federal Plaza on Nov. 26 flanked by advocates. The two were then separated, and the father was sent to Orange County Correction Facility — some 65 miles away.

Spector says she spoke to Zheng in person after his arrest.

“He said to me, ‘I did what they said I should do. I came in for this check-in.’ And yet they arrested him and his son,” Spector said.

In a statement, a spokesperson for the Department of Homeland Security denied these claims, saying, “ICE does not separate families… Mr. Zheng had the right and the ability to depart the country as a family and willfully chose to not comply.”

“For them to say they don’t separate families is just an outright lie because we know that they do and they did in this situation. And we know that they’ve done it with many other families,” Spector said.

Spector says last week’s arrest was the third time Zheng and his son had been held by ICE since crossing the border last spring.

They were paroled in late October and have spent the last month establishing a life in Queens. ICE maintains that it does not detain unaccompanied children except in rare instances.

“This is the case for so many of these families and individuals who are going in and following immigration law as mandated, yet they’re being arrested and detained and being disappeared. Right now, his son is disappeared,” Spector said.

Mayor-elect Zohran Mamdani condemned the arrest on social media, writing, “Six-year-old Yuanxin had just enrolled in the first grade at an elementary school in Astoria. Now he’s in custody, alone. ICE won’t say where. This cruelty serves no one. It must end.”

“I’m sure he was really enjoying being in school and that’s where he should be. That’s where a six-year-old should be — with other children and learning and being with their parents and not separated and in detention,” Spector said.

She says advocates are working on getting legal support and support from local elected officials to try to release Zheng from ICE detention and reunite him with his son.
