On September 16 , 1920 , close to the corner of Wall and Broad Street , the busiest corner of the financial district and across the offices of the Morgan Bank , a powerful bomb exploded . It killed 38 and seriously injured 143 people . The perpetrators were never identified or apprehended . The explosion did , however , help fuel the Red Scare that was underway at the time . A report from '' The New York Times '' : The area was subjected to numerous threats ; one bomb threat in 1921 led to detectives sealing off the area to " prevent a repetition of the Wall Street bomb explosion "
