Massachusetts police say three swastikas were found carved into a desk inside a high school on the first day of Hanukkah.

Andover High School Principal Philip Conrad announced Tuesday that the school will be working with police, local faith leaders and the Anti-Defamation League of New England to denounce the hateful graffiti. The Eagle-Tribune reports this is not the first time the school has dealt with swastika graffiti, as there have been several incidents this year.

Police Lt. Edward Guy called the graffiti disturbing and unacceptable, noting that drawing swastikas is a hate crime.

Andover High officials contacted the Anti-Defamation League on Tuesday to discuss response strategies.
