(JNS.org) The Boston-based New England Holocaust Memorial was vandalized Monday for the second time this summer.

A 17-year-old male reportedly threw a rock at one of the memorial’s glass panels, shattering it to pieces, before being tackled by two bystanders and held at the scene until police arrived.

The suspect was charged with willful destruction of property, and police are investigating whether the vandalism will be classified as a hate crime.

“Today and every day Boston stands up against hate. I’m saddened to see such a despicable action in this great city,” Boston Mayor Martin J. Walsh wrote on Twitter.
