The Pittsburgh Department of Public Safety and the Pittsburgh police are investigating the distribution of anti-Semitic pamphlets in the city's neighborhoods. 

"The Pittsburgh Department of Public Safety and the Pittsburgh Bureau of Police are aware of and are investigating the dissemination of anti-Semitic pamphlets in Pittsburgh neighborhoods, including Squirrel Hill," the department said in a statement shared on Twitter on Sunday. 

Squirrel Hill is the Pittsburgh neighborhood where a gunman opened fire at a synagogue in October, killing several congregants.


"Such hate-filled material will not be tolerated in Pittsburgh — not by residents, city officials nor Law enforcement," the statement added. "The Department of Public Safety assures the community that we are taking this matter very seriously and will follow every investigative avenue."

"Pittsburgh is and will remain stronger than hate."

The department of public safety did not provide details about the contents of the pamphlets, or the specific locations in which they were found. 

In late October, officials said Robert Bowers, 46, shot and killed 11 people at the Tree of Life synagogue in what the Anti-Defamation League called one of the deadliest attacks against the Jewish community in U.S. history. 

According to an arrest affidavit, Bowers told police that he wanted all Jews to die because they were "committing genocide to his people."

Bowers has pleaded not guilty to 44 federal charges related to the attack, according to reports.
