Boston’s New England Holocaust Memorial was targeted by a rock-throwing vandal for the second time in two months last night, when a teen shattered a glass panel etched with the numbers that Nazis tattooed on concentration camp victims, police said. 
 
 Police were called about 6:40 p.m. to the downtown landmark and said witnesses helped them identify a 17-year-old suspect. 
 
 The suspect’s name was not released because he is a juvenile. He is due to be arraigned today in Boston Municipal Court. Police were investigating the motive. ||||| The New England Holocaust Memorial in Boston was vandalized on Monday. 
 
 For the second time this summer, the New England Holocaust Memorial in Boston was vandalized when a 17-year-old allegedly threw a rock Monday evening through one of the glass panels, shattering it. 
 
 The male teenager, who is from Malden, was quickly tackled by two bystanders and held until police arrived. He is charged with willful destruction of property, and police are investigating whether the incident was a hate crime. 
 
 The vandalism, which happened just before 7 p.m., came just two days after a white nationalist rally in Charlottesville, Va. turned violent, and less than two months after a 21-year-old with a history of mental illness shattered a glass panel at the Boston memorial.

 The glass towers of the memorial, which was installed in 1995, had never been vandalized before the June incident.

 “It’s a reminder that we as a community need to be united, both in our opposition to all forms of hate but also in the important role that memorials play in our community,” said Robert Trestan, regional director of the Anti-Defamation League. 
 
 Trestan said it was important to let the investigation unfold before jumping to conclusions, but said the destruction was jarring, no matter what the suspect’s motive was. 
 
 “It’s a second blow to the community, and it comes at a time when most of Boston is standing in solidarity [against] the hatred that we saw in Charlottesville over the weekend,” he said. 
 
 On Twitter, Mayor Martin J. Walsh of Boston wrote: “Today and every day Boston stands up against hate. I’m saddened to see such a despicable action in this great city.”

 In a statement, Boston Police Commissioner William Evans said “Clearly, this type of behavior will not be tolerated in our city. And, in light of the recent events and unrest in Charlottesville, it’s sad to see a young person choose to engage in such senseless and shameful behavior.” 
 
 At the memorial, police tape cordoned off two of the glass towers, and public works crews scooped up the glass with shovels. 
 
 Jeremy Burton, the executive director of the Jewish Community Relations Council, noted that the memorial in Boston stood for two decades before it was vandalized. 
 
 “It’s shocking and it’s particularly shocking for us in the Jewish community, coming as it does in a week in which so many of us spent our weekend watching Nazis marching in Virginia.” 
 
 Keith Bedford/Globe Staff Investigators looked at glass sitting on the ground after it was vandalized. 
 
 Burton said the panels on the memorial are made from a “very resilient” glass.

 “I can only say from what I know of the June attack, it takes a very, very conscious effort to break this glass,” he said. 
 
 Austin Giles was passing through the memorial and reading the panels, which bear numbers representing victims of the Holocaust, when he heard glass shatter on the opposite end. He saw police take the suspect into custody. 
 
 “I was just walking through and observing,” said Giles, who lives in Marshfield. “My first instinct was, what the hell? Did a rock hit it or something? I couldn’t fathom somebody would possibly do this.” 
 
 Scott Strauss and his family, who are visiting from Miami, said his grandparents on both sides of his family were Auschwitz survivors, and he wanted to show the memorial to his children. 
 
 Walking past the scene, Strauss explained to his 6-year-old that the memorial was for “grandpa.” 
 
 “It’s just awful,” he said. 
 
 “This right here doesn’t represent the city of Boston,” Strauss said. “It represents hate and evil.” 
 
 Natalia Pfeifer, 23, of New Jersey, said she was across the street with a friend in front of the Boston Public Market when she heard a “big shattering sound.” 
 
 When they went to cross the street, Pfeifer said, she and her friend saw a man with a hooded jacket standing right where the glass was. 
 
 According to Pfeifer, the man put up his hood and ran through the memorial and across the street before he was tackled. 
 
 Danielle Souza, 27, of Everett, said the timing of the vandalism was distressing. 
 
 “Especially with everything going on right now, it breaks my heart,” Souza said. 
 
 The memorial reopened around 9 p.m. A family with young children was the first to walk through. 
 
 “It’s for the Holocaust,” the adults explained. 
 
 Police said that at least one officer would be posted at the memorial throughout the night. 
 
 Keith Bedford/Globe Staff Employees cleaned up the shattered glass at the memorial.

– A holocaust museum in Boston was vandalized for the second time this summer, and this time bystanders tackled the alleged vandal. Boston police say a 17-year-old shattered a glass panel of the New England Holocaust Memorial with a rock, reports the Boston Herald. The panel contained etchings of the numbers that Nazis tattooed on their Jewish prisoners. Witnesses tackled the teen, who's not being identified because he's a juvenile, and held him until officers arrived, reports the Boston Globe. He's been charged with willful destruction of property, and police are investigating his motive to see whether hate crime charges are warranted in the Monday evening incident. "It's incredibly disturbing ... coming as it does two days after Holocaust survivors had to witness people marching through the streets of Charlottesville, Va., chanting Nazi slogans," says Jeremy Burton of the Jewish Community Relations Council, which manages the site, per the Herald. Boston's police chief also drew a comparison to Charlottesville and said it's "sad to see a young person choose to engage in such senseless and shameful behavior." In June, a 21-year-old was charged with breaking one of the memorial's 132 panels, also with a rock. Prior to that incident, the memorial's panels had stood undisturbed for more than two decades.
