An U.S. Marshals Service official in the Southern District of New York was sentenced to almost four years in prison for giving one of his guns to a convicted felon and committing perjury, the New Jersey U.S. Attorney announced Thursday.

Deputy U.S. Marshal Antoine Dobson gave his off-duty firearm to Larry Langforddavis and provided false statements to a federal grand jury investigating the crime.

Dobson received a 45-month prison sentence, in addition to three years of supervised release.
