Greater than 1,000 stickers had been placed on gravestones and picket crosses at three cemeteries within the southern German metropolis of Munich.
The stickers, which have been placed on each previous and up to date graves, have a QR code that when scanned reveals the title of the particular person buried and the situation of their grave within the cemetery.
The 5×3.5-centimeter (1.95×1.2-inch) stickers surfaced in current days on the Waldfriedhof, Sendlinger Friedhof and Friedhof Solln cemeteries.
Police are investigating the incident.
“We haven’t found any pattern behind this yet. The stickers were put both on decades-old gravestones and very new graves that so far only have a wooden cross,” police spokesperson Christian Drexler stated.
“People who have witnessed anybody putting the stickers on the graves are asked to reach out to the respective cemetery’s administration,” Mr Drexler stated.
