TRENTON, NJ—A Jersey City man was sentenced today to 114 months in prison for committing an armed robbery of a jewelry store in Hudson County, New Jersey, U.S. Attorney Paul J. Fishman announced. Mouhamadou Lamine Amar, 21, previously pleaded guilty before U.S. District Judge Mary L. Cooper in Trenton federal court to an indictment charging him with committing a Hobbs Act robbery and with brandishing a firearm during the robbery. Judge Cooper imposed the sentence—which includes 30 months on the robbery count and 84 months, served consecutively, on the weapons count—today in Trenton federal court.

According to documents filed in this case and statements made in court:

On June 28, 2013, Amar entered a jewelry store in Jersey City and held a gun to a store employee’s head. He grabbed and pushed the employee when the employee tried to flee. He tied up the employee and threatened to shoot the employee if the employee tried to escape. Amar was arrested inside the store while still in possession of the firearm.

In addition to the prison term, Judge Cooper sentenced Amar to three years of supervised release.

U.S. Attorney Fishman credited special agents of the FBI, under the direction of Special Agent in Charge Aaron T. Ford in Newark, with the investigation leading to today’s guilty plea. He also thanked the Jersey City Police Department and the Hudson County Prosecutor’s Office for their work on this case.

The government is represented by Assistant U.S. Attorney Andrew Kogan of the U.S. Attorney’s Office Criminal Division in Newark.
