BANGOR — A Bangor man authorities say fired as many as 70 shots from his apartment window during a standoff with police, forcing the city’s Fourth of July parade to be rerouted, has pleaded not guilty to federal firearms charges.

Oliver Perrin remains in federal custody after his appearance Wednesday in U.S. District Court in Bangor.

The 43-year-old Perrin is charged with being a felon in possession of a firearm.

WABI-TV reports that according to court documents, Oliver was not allowed to have guns due to a conviction in 2008 in New York.

The four-hour standoff ended when a tactical team used tear gas to take him into custody. No one was hurt.

Oliver was charged in state court with criminal threatening and reckless conduct with a firearm.
