An Afghan national living in Oklahoma City was arrested and charged for allegedly plotting to carry out a terrorist attack on Election Day in support of ISIS, the Justice Department announced Tuesday.

Nasir Ahmad Tawhedi, 27, was arrested by the FBI after the agency allegedly discovered he had acquired AK-47 firearms and ammunition for the plot. In preparation for the attack, Tawhedi took steps to liquidate his family’s assets and resettle his family members to live overseas, according to a press release sent out by the Justice Department.

“As charged, the Justice Department foiled the defendant’s plot to acquire semi-automatic weapons and commit a violent attack in the name of ISIS on U.S. soil on Election Day,” Attorney General Merrick Garland said. “We will continue to combat the ongoing threat that ISIS and its supporters pose to America’s national security, and we will identify, investigate, and prosecute the individuals who seek to terrorize the American people.”
