The 911 call that prompted police to shut down a part of Tenth Avenue as they investigated the report of a man with a gun hiding in a building has been deemed unfounded.
Tenth Avenue between 45th and 47th streets was closed early Monday evening as police investigated the 911 report. It has since reopened to traffic.
An NYPD spokesman said there was no evidence of a gunman at 550 West 45th St., and the call was believed to be a hoax, but police continuted to sweep the area until they could clear it.
Neighbors reported heavy police presence -- one posted a photo to Twitter showing a police sniper on a roof at 45th Street near 11th Avenue. Armored trucks and tactical teams from the Emergency Services Unit were also on scene.
Workers in nearby office buildings reported being placed under lockdown as NYPD swarmed the area.
The police spokesman someone called police to report a possible gunman on a roof, and then hung up. When police called him back, they got a fake number.
