ROTTERDAM - Police say a World War II style grenade that a woman discovered  Tuesday morning while cleaning out her father-in-law's home turned out to be harmless.

Shortly after 9 a.m. Tuesday, she had called Rotterdam police who contacted the State Police Bomb Squad.

State Police  later removed the ordnance from the home at 1065 Spry Lane in Rotterdam's Coldbrook neighborhood.

A town police spokesman said in a news release that the grenade was likely a souvenir or keepsake but that the woman's father-in-law, who is still alive, refused to talk about it.
