An Adams, Massachusetts, man accused of plotting to attack a college on behalf of the self-declared Islamic State has pleaded not guilty. Twenty-three-year-old Alexander Ciccolo was arraigned Wednesday at federal court in Springfield.

Ciccolo, who’s father is a Boston police captain, pleaded not guilty to a guns charge. An FBI witness gave Ciccolo four guns, and prosecutors say a previous conviction made his possession of firearms illegal.

He’s also accused of attacking a nurse at the Franklin County jail. Ciccolo’s attorney David Hoose previously said his client regrets hurting the nurse, but pleaded not guilty to keep his options open for a defense.

Hoose says he does not know if the government will also file terrorism charges.

“I know they’re looking into additional charges,” Hoose told reporters after the brief hearing. “Whether they’re there or not is something the governmentis going to have to determine.”

Prosecutors have said Ciccolo had partially made Molotov cocktails in his apartment and bought a pressure cooker with the intention of turning it into a homemade bomb.
