 A group of Hasidic Jewish worshipers were arrested amid a dispute over a secret tunnel built beneath a historic Brooklyn synagogue, setting off a brawl between police and those who tried to defend the makeshift passageway. Video from the Habad Lubavitch World Headquarters in Crown Heights on Monday showed officers removing a man from a tunnel built into the synagogue when a group of onlookers begin shoving police and tossing wooden desks.A spokesperson for Habad said a group of extremists. Students had broken through the walls of adjacent properties and Monday's standoff began after leadership brought in a construction crew to repair the damage to IT wasn't immediately clear why or when the tunnel was constructed. Empty space nearby. The synagogue's leaders apparently discovered the tunnel in the last few weeks and on Monday they sent a cement truck to repair the walls. When they did that the Hasidic students who supported the tunnel staged an impromptu protest getting inside the passage and refusing to leave. Video showed that some people apparently shoved cops, others lifted these prayer desks into the air. As a result nine people were arrested, three were issued disorderly conduct summonses and as of this week the city is still making sure that the structural foundation of the synagogue is intact.
