Alexander Castellanos, 33, was initially sent to the Bergen County Jail on aggravated assault charges following his weekend arrest, records show.
Fairview police said Castellanos punched the 20-year-old victim in the face, sending him to the hospital with was believed to be a broken nose.
The victim obtained a temporary restraining order, they said, but that won't be necessary now.
Within hours of being booked into the county lockup on aggravated assault charges, Castellanos was scooped up by federal agents on Sunday, Dec. 5, police said.
He remained in their custody while a deportation hearing before an immigration judge in Newark was being arranged, authorities said.
