A doctor is dead after shooting six people inside Bronx-Lebanon Hospital Center Friday afternoon, killing at least one victim.
Hospital security and police were going floor by floor at around 3 p.m. Friday trying to locate the shooter, who was wearing a white lab coat when he opened fire on one of the hospital's upper floors, according to NBC New York.
The shooter is confirmed dead due to a self-inflicted gunshot would, according to the NYPD. He was identified as Dr. Henry Bello, 45, a former employee of the hospital.
The victims "are fighting for their lives right now," said New York City Mayor Bill de Blasio.
"There are many, many details that we are still putting together," he added in a news conference Friday afternoon. "That's why we are not in a position to answer questions yet."
De Blasio went on to commend the NYPD and the hospital's workers for their heroic actions during the ordeal.
Dr. Bello reportedly hid the rifle under a lab coat when he entered the hospital and opened fire on the 17th floor.
"It now appears you have what could almost be described as a classic lone-wolf...workplace violence incident," Former NYPD Commissioner Bill Bratton told NBC, "something that is very common in our country."
There were 417 people murdered in workplace violence in 2015, Bratton said, citing statistics from the Occupational Safety and Health Administration.
Bratton added that the AR-15 rifle Bello allegedly used is one NYPD officers rarely see used in city incidents.
The condition of the rest of the victims was unknown, reports ABC 7 New York.
The hospital was under lock down.
Mayor Bill de Blasio has been briefed on the situation, according to the mayor's office.
This is a developing story.
