(JNS.org) Levi Rosenblat, a 22-year-old Israeli yeshiva student, was wounded early Tuesday morning in a stabbing at Chabad-Lubavitch headquarters in the Crown Heights section of Brooklyn, N.Y.

Police said that 49-year-old Calvin Peters entered Chabad headquarters around 1:40 a.m. on Tuesday and stabbed Rosenblat several times in the upper body.

Rosenblat, who is Beitar Illit in Judea and Samaria, was reported to be conscious and in stable condition.

According to Chabad-Lubavitch spokesman Rabbi Motti Seligson, Rosenblat had been studying inside of the synagogue when he was attacked.

Police said that Peters threatened to “kill all of you,” while Seligson said that witnesses heard the man saying repeatedly, “Kill the Jews.”

Police inside of the synagogue confronted the assailant and told him to put the knife down on a table. But after putting it down, Peters then grabbed the knife and lunged at one of the officers, who fired once, hitting the suspect in the torso, CBS New York reported. Peters was later pronounced dead at the hospital.

Seligson said that the attack was most likely not terror-related or a hate crime. He added that many “borderline homeless” people visit the headquarters at night to warm up and that there was likely “an unpleasant exchange” between Peters and Rosenblat, after which “the stabber took out a kitchen knife and screamed at the Jewish youth that he would kill him.”

“I’m told that the attacker came earlier that evening, too. He was stalking the scene,” New York State Assemblyman Dov Hikind said in a statement. “Thank God he didn’t inflict more harm nor do more damage to more people.”

Police said that Peters was known to authorities as being an emotionally disturbed person.

“While we are very pained by everything that has unfolded, we are very grateful to the police for their quick response and are working closely with the authorities in their ongoing investigation,” said Seligson.
