A Stamford man was sentenced to two years in federal prison Monday for unlawful possession of a firearm after police found a loaded Glock 9-millimeter in his home in 2020, according to the U.S. Attorney’s Office.

Amin Hasan, 44, of Stamford was sentenced to 24 months of imprisonment, followed by three years of supervised release. U.S. District Judge Michael P. Shea ordered Hasan to serve the first six months of his supervised release in a halfway house.

Hasan was arrested on Dec. 5, 2020, after causing a disturbance at a shopping center, according to the U.S. Attorney’s Office. Police searched a van he had rented and found 13 filled five-gallon gas cans, two hatchets, an ax and other items, the U.S. Attorney’s Office said.

Police then searched his home the next day and seized a gas mask, chainsaw, survival-style knife, backpacks filled with 30 smoke grenades and 44 tire-puncturing spikes. There was a note on his bed saying to call his cousin in the event of his death, the U.S. Attorney’s Office said. Police also found the gun he was later sentenced for, the U.S. Attorney’s Office said.

Officers also found Hasan’s car parked in Bridgeport days later and it had another 12 filled five-gallon gas cans and another hatchet, among other items, the U.S. Attorney’s Office said.

Hasan was previously convicted in May 2019 of assault on public safety emergency medical, public transport or health care personnel, according to court records. It is against federal law for a previously convicted person to possess a firearm or ammunition that has been transported across state or federal lines, the U.S. Attorney’s Office said.

Hasan has been in police custody since his arrest. He pleaded guilty to unlawful possession of a firearm by a felon on May 6, the U.S. Attorney’s Office said.

Related state charges against Hasan are pending. Those charges include four counts of assault on public safety emergency medical, public transport or health care personnel and three misdemeanors in connection with the incident on Dec. 5, 2020. He has a $1.5 million bond in that case and has pleaded not guilty to all charges, according to court records. He was also charged by the state with criminal possession of a firearm, ammunition or a defense weapon and stealing a firearm after police. He has a $250,000 bond in that case and pleaded not guilty to those charges as well.
