No injuries were reported.
Traffic was halted in the area, near 112th Street and Liberty Avenue in South Richmond Hill, after a call about the suspicious device came in around 11:20 a.m. A cleaning crew was working in a building when they saw what looked like a grenade inside a plastic bag, so they brought it outside and called police to alert them about the potentially explosive discovery.
A bomb squad truck and other emergency vehicles were seen parked under an elevated subway track. The MTA said trains on the A line were bypassing that station as a precaution for more than an hour, but regular service resumed shortly after 2 p.m.
Law enforcement sources said investigators were trying to determine just how the device got to the location. The bomb squad said the grenade was inert. It was taken to a secured location in the Bronx for a closer look.
