CONCORD, N.H. — The U.S. Immigration and Customs Enforcement Agency is taking steps to ensure a Ukrainian-born truck driver whose collision with motorcyclists in New Hampshire left seven dead remains in custody even if his criminal case were dismissed.

Twenty-three-year-old Volodymyr Zhukovskyy is being held without bail in the Coos County House of Corrections. He pleaded not guilty Tuesday to negligent homicide in Friday’s crash .

Zhukovskyy’s father told the Boston Herald that his son is a Ukrainian citizen and has permanent resident status in the U.S.

Jail Superintendent Ben Champagne said ICE placed a detainer on Zhukovskyy on Tuesday. A detainer means even if the case were to be dismissed, Zhukovskyy would be turned over to ICE for possible deportation.
