An extremely large, disorderly crowd at Pier 2 in Brooklyn Bridge Park prompted police to call a Level 1 Mobilization and evacuate sections of the park shortly before 4 p.m. on Tuesday.

Thousands of park-goers streamed out of the park along the Joralemon Street and Old Fulton Street exits, or headed along Furman Street to Atlantic Avenue. Traffic in Downtown Brooklyn was jammed as emergency vehicles tried to get to the park.
