Police said vandals toppled 19 headstones at a Jewish cemetery in Worcester County.
Auburn Police Chief Andrew Sluckis estimated the cost of the damage at the Worcester Hebrew Cemetery discovered earlier this week at $15,000.
Of the 19 headstones knocked over, two were cracked in half.
Sluckis said some evidence has been recovered at the scene.
Jordan Robbins, co-chairman of running the cemetery for the Jewish Federation of Central Massachusetts, told The Telegram & Gazette that the federation is offering a $500 reward for information leading to an arrest and conviction.
The cemetery was also vandalized around the Memorial Day weekend, when eight headstones were knocked over.
