In this regard, the organizers were forced to cancel the event, which was held on the territory of a synagogue in Murmrr Theatre under the guidance of the star of the sitcom "broad city", Ilana Glazer.
James Polite, 26, is charged with four counts of criminal mischief as a hate crime and making graffiti.
Glazer told the crowd of 200 people who had lined up that the event had to be cancelled due to safety concerns, Democracy Now reports.
Police said "Hitler" was found written on the first-floor staircase, and the message "Jews better be ready" was found on the third-floor staircase.
The suspect reportedly was admitted to a hospital psychiatric ward for observation.
Also this week, authorities said a synagogue in Irvine, California, had been vandalized with anti-Semitic graffiti.
Police said there were also drawings of the Puerto Rican flag, and the words "Free PR" were written in black marker on walls.
Glazer was scheduled to speak at the Union Temple Synagogue in Brooklyn's Prospect Heights neighborhood, along with moderator Amy Goodman and NY state Senate candidates Andrew Gounardes and Jim Gaughran. "We will continue to learn, organize and act and make this country as safe for as many people as possible".
Mayor Bill de Blasio joined the Union Temple congregation for Shabbat services Friday as a show of solidarity.
Police on Friday arrested a suspected arsonist in the setting of fires targeting seven Jewish locations and writing anti-Semitic graffiti in the largely Hasidic section of South Williamsburg, Brooklyn.
However, the attacks received relatively little publicity before the mass murder at the Tree of Life Synagogue in Pittsburgh focused the nation's attention on incidents of anti-Semitic hate crime.
Less than a week before the Brooklyn anti-Semitic incident, 11 people were killed in the Tree of Life Synagogue in Florida, on October 27.
"Following in the wake of the Union Temple hate incident, antisemitism strikes again, this time in Williamsburg", City Councilman Stephen Levin wrote on Twitter Friday.
