A callous thief ripped off an urn filled with a dearly departed’s ashes from a Long Island driveway, police said Friday.

The crook swiped the gilded, decorated urn sometime between 9:45 p.m. July 22 and 7 a.m. the next day from inside a 2010 Chrysler that was parked in the driveway of a home on Elkon Lane North in North Babylon, Suffolk County police said.

CrimeStoppers provided a photograph of the urn, which cops said was worth approximately $100.

Authorities are offering a $5,000 cash reward to anyone with information that ultimately leads to an arrest.
