The Schenectady man accused of firing shotgun rounds outside of Albany's Temple Israel last week faces an additional firearms charge, federal authorities said Monday.

Mufid Fawaz Alkhader, 28, was charged Monday with conspiracy to make a false statement during the purchase of a firearm, in addition to Friday's charge of possessing a firearm as a prohibited person, U.S. Attorney Carla Freedman, the ATF and FBI said in a joint statement.

Law enforcement officials say the latest charge stems from Alkhader obtaining a shotgun he allegedly fired outside the synagogue about a month ago by giving a friend money to purchase it for him because he believed he was potentially ineligible to purchase it himself due to a prior order of protection or restraining order.

The friend purchased the gun for $599.99 at a licensed firearms dealer in Albany County, and lied on an ATF form by checking a box “Yes” when asked if he was buying the firearm for himself, before giving the shotgun to Alkhader, Freedman said.

The police statement didn't identify the friend. 

Alkhader twice fired a Kel-Tec KS7 12-gauge pump-action shotgun into the air outside the synagogue on Thursday afternoon, according to police. Albany police officers arrested Alkhader, who police say was prohibited under federal law from possessing the shotgun because he was an unlawful user of a controlled substance, in his case, marijuana.

The case is being investigated by the ATF, the FBI’s Joint Terrorism Task Force and the Albany Police Department.

If convicted of the charges, Alkhader faces up to 20 years in prison, according to federal law enforcement officials.
