At least two people have been injured in a shooting at a hospital in the Bronx area of New York, police confirmed Friday. The gunman was dressed in a lab coat when he shot several people shortly before 3 pm (1900 GMT) at Bronx Lebanon Hospital, according to reports from broadcaster NBC New York. Updating former news, police said a rogue gunman killed a doctor and injured several others before turning his gun on himself at a hospital in the Bronx area of New York Friday. One female doctor was dead and five other victims were in the emergency room after the former employee at Bronx Lebanon Hospital opened fire just before 3 pm (1900GMT), Police Commissioner James O'Neill said at a press conference. The hospital's fire alarm system activated as the suspect, a former employee at the hospital, tried to set himself on fire, O'Neill said. Police found the suspect dead at the scene from an apparent self-inflicted gunshot wound. He was wearing a white medical coast and a rifle was found nearby. Local media named the suspected gunman as 45-year-old Dr Henry Bello, a family medicine doctor formerly employed at the hospital, but O'Neill declined to officially identify him. NBC New York reported that Bello resigned from the hospital in 2015 in lieu of being fired, dpa reported. New York Mayor Bill de Blasio thanked police officers and first responders for their "heroism" in evacuating the hundreds of people in the building. "Thank God this was not an act of terrorism, it's an isolated incident, it appears to be a workplace-related matter, but that makes it no less tragic or horrible," de Blasio said according to dpa. "This was a horrific situation unfolding in the middle of a place that people associate with care and comfort, a situation that came out of nowhere."
