CHICAGO (FOX 32 News) -
A Chicago man pleaded not guilty to charges of falsely making a terrorist threat Tuesday.
Prosecutors said 24 -year-old Sebastian Senakiewicz threatened to blow up a train overpass during the NATO summit in May. They said he bragged to friends that he was going to use a car full of explosives during the summit.
The Poland-born man is also accused of bragging about hiding explosives in a hollowed-out Harry Potter novel.
Defense attorney Melinda Power has said her client may only have been ranting and boasting wildly while he was drunk.
When police arrested Senakiewicz, they searched his apartment but did not find any weapons.
He is being held at the Cook County Jail on $750,000 bond.
Senakiewicz is one of four protesters arrested before the May summit and charged under a never-before-used Illinois terrorism statute. The others have also pleaded not guilty.
All four suspects have been unable to raise bond money and remain jailed.
