OGDENSBURG -- The 400 block of Mansion Avenue was closed off and residents were asked to shelter in place Sunday as Ogdensburg police and firefighters worked to remove a World War I-era 75MM anti-personnel artillery round from 407 Mansion Ave.

Police were called to the residence at 6:43 p.m. after someone reported “two fire extinguishers and a cylinder of gun powder."

After arriving on the scene, police took possession of what they determined was Scovil Model 1907 artillery round.

Police initially blocked off the 400 block of Mansion Avenue and asked residents to shelter in place at the rear of their residences.

Police asked Ogdensburg Fire Department to stay in the area as a precaution, and contacted New York State Police Bomb Disposal Unit.

"After police spoke with the bomb tech, it was determined the restrictions could be loosened," a release from Ogdensburg police said.

An officer remained on site with the ordinance until a member of the bomb disposal unit arrived to remove it.

Police say an initial inspection revealed the round to appear live. Police will test the shell and then it will be destroyed, according to the press release.

A statement from Ogdensburg police offered appreciation to the New York State Police for their assistance.
