Kildare gardaí are advising people not to leave valuables in their cars, or keep them out of sight, while visiting graveyards.
The warning comes following a number of thefts.
More families are tending to graves of loved ones at this time of year in advance of annual blessing ceremonies at cemeteries.
Last month, a car parked outside the graveyard at Dublin Road, Athy, reported a white hatchback with a Northern Ireland registration, and returned later to find that her handbag was stolen from the car.
In May, a woman returned from visiting her grandmother's grave at the Abbey Graveyard, Kilcullen, to discover that the window of her car had been smashed.
A Kildare Garda spokesman said: ”Keep property out of sight in cars while visiting graveyards, and do not leave valuables in vehicles at all if possible."
