U.S. Immigration and Customs Enforcement (ICE) detained a Michigan doctor last week who has been living in the U.S. for nearly forty years, according to Grand Rapids's NBC affiliate WOOD-TV.

Lukasz Niec, who came to the U.S. from Poland when he was five years old with his sister and parents, is being held at Calhoun County jail, according to the report.

Niec's sister told WOOD-TV that the family does not know when he will be released from jail.

“Until this gets heard, which could be up to six months, he could be stuck in a prison cell and not helping and being with his family,” Iwona Niec-Villaire said.

The news outlet reported Niec was convicted when he was 17 on one charge of destruction of property less than $100 and receiving and concealing stolen goods.

Niec reportedly pled guilty to the charges under the Holmes Youthful Trainee Act, which helps young first-time offenders keep charges off of a criminal record, but ICE does not honor the state plea agreement.

The arrest comes as the immigration debate, particularly over the Deferred Action for Childhood Arrivals program, plays out on the national stage.

Senate Republicans and Democrats failed on Friday to reach a midnight deadline to fund the government, causing a shutdown.

A majority of Democrats voted against the GOP funding measure because it did not contain a fix for the program.

Republicans have in turn accused Democrats of holding the government hostage.
