(JTA) – Unidentified perpetrators spray painted the words “kill Jews” and a white supremacist slogan on headstones at a cemetery in Cape Cod. Several headstones were knocked over at Oak Neck, a 5.5-acre graveyard that is the only active cemetery in the village of Hyannis, 70 miles southeast of Boston, Fox25 reported last week. Oak Neck is not a Jewish cemetery. Police in Barnstable are treating the investigation as a hate crime, Fox25 reported.

About a dozen or more tombstones were either kicked over or otherwise vandalized. Some of the graffiti was directed at police officers. One headstone was defaced with the number 666, a number association with Satanic groups. Another featured the numbers “4.20,” ostensibly a reference to Adolf Hitler’s birthday. The incident comes amid an increase in hate crimes in some parts of the United States following the November election.
