The demolition of a so-called "zombie house" on Halloween led to the discovery of live hand grenades at the site Thursday morning in Rocky Point, according to Suffolk County police.
The department said Emergency Service Section officers responded to the abandoned home on King Road following a 911 call at 10:07 a.m. reporting the discovery.
Officers removed five grenades, which workers had dug up in a bag, to be detonated off-site. Three of the five grenades were later found to be live, according to the department.
The police did not say whether the grenade owner or owners have been identified, whether the devices are legal or whether there could be a criminal charge.
Town of Brookhaven spokesman Jack Krieger said the grenades were discovered by Panzner, the East Patchogue-based contractor hired to demolish the home as part of their zombie house reclamation project.
He said the home was owned by a bank. He said he didn't immediately know which one.
