A Confederate flag was tied to the front of the Museum of Jewish Heritage in New York, according to a police report.
An aggravated harassment complaint has been filed, but no arrests have been made, police added.
“The Confederate flag is a symbol of hate. This week it was paraded through the Capitol and this morning it was used to vandalize the Museum of Jewish Heritage in our city,” Mayor Bill de Blasio tweeted.
“We have ZERO tolerance for acts of fascism and bigotry,” the mayor added, vowing that “there will be consequences for those responsible.”
“This is an atrocious act on our community and on our institution and must be met with swift and forceful response from law enforcement,” Jack Kliger, the president and CEO of the museum, said in a statement.
“The Confederate flag is a potent symbol of white supremacy, as evidenced by the events at the U.S. Capitol this week. Such hate has now arrived at our doorstep.”
