A hand grenade was found on a South Farmingdale street Friday and removed by a robot controlled by bomb squad officers, Nassau police said.
A pedestrian spotted the grenade about 12:15 p.m. on Heisser Lane near Heisser Court, police said. It was on the roadway, not far from the curb and a Long Island Rail Road overpass, police said.
A police spokesman said he did not know whether the grenade was live.
The area, which has several condo buildings and a few businesses, was evacuated as the bomb squad's robot removed the grenade for proper disposal, police said.
By midafternoon the object was taken away by police to be examined, said rail spokesman Salvatore Arena.
Farmingdale Mayor Ralph Ekstrand said the area reopened about 3:45 p.m.
He said a village code enforcement officer at the scene told him that officers there confirmed it was a grenade.
The object was not on MTA property but in an area that borders LIRR tracks connecting the Babylon branch to the Main Line, Arena said.
Passenger service was not affected, he said, but at the time the object was found, a New York and Atlantic Railway freight train was on the tracks.
Nassau police asked MTA to shut down power to the tracks so that authorities could investigate, Arena said, and the freight train had to stop in its tracks.
The freight train was carrying construction and demolition debris from Lindenhurst to Queens, said Jay David Wallace, superintendent of the New York and Atlantic Railway, based in Queens.
It was stopped short of the area where the object was found and delayed for about 20 minutes, Wallace said.
