Swastikas and graffiti, some of it anti-Semitic, were painted on the wall of a public high school in Stamford, Connecticut, JTA reported on Wednesday.

The vandalism was discovered on Saturday morning at the Academy of Information Technology and Engineering and was the second act of anti-Semitic vandalism to occur this summer in Stamford.

In July, a city resident used feces to smear a swastika and a Star of David in the window of a television station downtown.

In addition, there have been reports of two people being called anti-Semitic slurs while leaving local synagogues in the past two weeks, saud the United Jewish Federation of Greater Stamford, New Canaan and Darien.

“We cannot and will not tolerate hate in our community,” the federation said in a statement quoted by JTA.

“We call on faith leaders to come together and speak out against hate. These hateful and disturbing acts are not just a Jewish problem, but one affecting all minorities,” it added.

The Stamford School District and the mayor both released statements saying it was important to condemn hate and racism, according to the local news Channel 12.

Elsewhere in Connecticut, some 60 headstones were toppled in a Jewish cemetery in Hartford last month.

The damage at the Ateres Knesseth Israel Cemetery was discovered when a relative of someone buried there visited the gravesite.
