The shootout that took place here Friday in front of the Empire State Building left two dead - one of them the attacker - and nine people injured, New York Mayor Michael Bloomberg said.
The assailant, 53-year-old Jeffrey Johnson, killed one person and was fatally shot by police responding to the initial shots, Bloomberg told a press conference.
Johnson's victim was a manager at Hazan Imports, the firm that laid off the shooter last year.
Describing the shooting as a "terrible tragedy," the mayor said the incident had "nothing to do with terrorism."
Also at the press conference was Police Commissioner Ray Kelly, who said that after killing his former coworker, Johnson put the gun, a .45 caliber pistol, in a bag and walked out, but a construction worker who saw what happened notified police guarding the entrance to the Empire State Building.
The cops followed the attacker, who took the gun out of the bag and started shooting, and the officers returned fire.
"New York City is the safest big city in this country but we are not immune to the national problem of gun violence," Bloomberg said.
A NYPD spokesperson had confirmed to Efe that the shooter was gunned down by police, who rushed to the scene of the incident in an area full of tourists after 9:00 a.m.
The injured have been taken to various Manhattan hospitals.
The shooting in one of the most-visited places in the city of skyscrapers sowed panic among the many pedestrians going to work at that hour, as well as among the many tourists present in the area. EFE
