Bello was was recently fired from his job at the hospital, law enforcement sources said.

Friday's hour-long shooting spree played out on the 16th and 17th floors of the facility, and ended when the gunman tried to set himself on fire, then shot himself, NYPD Commissioner James O'Neil said at a press conference held outside the hospital Friday.

Cops found both the shooter and one of his victims dead on the hospital's 17th floor, O'Neill said. Click here for Patch's developing report from the scene.

According to CBS, Bello was originally fired from Bronx Lebanon for harassing an employee.

"This was not an act of terrorism," NYC Mayor Bill de Blasio said Friday. He said the mass shooting "appears to be a workplace-related matter — but that makes it no less tragic and no less horrible."

The mayor called the shooting "a horrific situation unfolding in a place that people associate with care and comfort."

De Blasio also commended the hospital employees "whose day went from normal to horrifying in a matter of seconds" — and who "protected each other and protected their patients, even amidst this horrible situation."

Panicked social-media dispatches from inside the hospital Friday indicated the facility was on complete lockdown, with patients and employees hiding out in hospital rooms as they listened to the terrifying sound of gunfire nearby.
