Police in New York City are searching for a gunman who was caught on surveillance video casually strolling up to a group of people holding a vigil before opening fire and hitting one man in the chest. 

According to the NYPD, the shooting took place in front of 542 Gates Avenue in the Bedford-Stuyvesant section of Brooklyn just after 9.30pm on September 23. 

Several people were sitting on the sidewalk as part of a vigil when a man in a hooded sweatshirt and a mask walked up to them, with one hand tucked into his pocket and another holding a gun.
