Chaos erupted at the Chabad Lubavitch World Headquarters in Brooklyn on Monday as a group of Orthodox Jewish men attempted to prevent construction workers from sealing an illegally constructed secret tunnel. This led to clashes with police officers and resulted in the arrest of ten people. The tunnel, discovered in December last year, posed a risk to the building's foundation, extending from under the women's section of the synagogue to a mikvah—a Jewish cleansing bath. The incident went viral on social media showing the men tearing down wooden panels within the main synagogue and confrontations with law enforcement. The police worked swiftly to facilitate the construction crew's work, detaining the protesters who refused to vacate the underground passageway. The ownership of the synagogue building is under dispute between the Chabad-Lubavitch movement and the synagogue leadership. The incident has brought significant attention, highlighting the complex challenges surrounding the preservation of religious sites and the difficulties religious communities face in maintaining their properties. The Chabad-Lubavitch community has expressed distress at the vandalism and has vowed to restore the sanctity of the synagogue.
