Police said a grenade found on Massachusetts Avenue in Cambridge this morning had no gun powder and no detonator and was not a threat to the public.
But Cambridge Police did not know the grenade was not a threat when they shut down a portion of Massachusetts Avenue at Linnaean Street near Porter Square this morning.
Cambridge Police spokesman Dan Riviello said a pedestrian reported seeing the suspicious device on the street at 9:07 a.m. and reported it to police. (See photo gallery.)
The Cambridge Police Bomb Unit responded and shut down the roadway until the grenade could be safely removed. Riviello said police X-rayed the grenade to see if it was real or a toy. The X-ray revealed the grenade was real, but had no gunpowder or detonator.
Police interviewed the person who called 911, but don’t know how the grenade got in the street.
Riviello said the grenade appeared to be old and could date back as far as World War II It appeared to be “banged up” as if some vehicle may have run it over, he said.
