The man accused of firing off seventy rounds of ammunition in downtown Bangor on the 4th of July pleaded not guilty in federal court Wednesday morning.
Perrin Oliver, 43, is charged with being a felon in possession of a firearm.
According to court documents, Oliver was not allowed to have guns due to a conviction in 2008 in New York.
Police say he fired shots out a window of his park street apartment July 4th.
The tactical team eventually used tear gas to capture Oliver.
Oliver has also been charged in state court with criminal threatening and reckless conduct with a firearm.
The US Attorneys Office says Oliver is still in federal custody.
