"The swanky Back Bay nightclub where Patriots wide receiver Julian Edelman allegedly groped a young woman at a Halloween party is equipped with surveillance cameras that could help investigators determine what really happened that night, sources told the Herald.

The 25-year-old Patriot — who was at the holiday party at the upscale club Storyville dressed as a "Reno 911!" spoof cop — pleaded not guilty to one charge of indecent assault and battery yesterday and was ordered to stay away from the bar and the alleged victim.

Investigators yesterday were studying tapes of the late-night Halloween party taken from the Exeter Street club's surveillance cameras, according to one of the sources."
