A Nigerian-born gunman, Henry Bello has killed a doctor and injured six others after opening fire inside a hospital in Bronx, New York, US.
The gunman killed himself after the shooting spree which took place Friday on the 16th and 17th floors of the Bronx-Lebanon Hospital.
Bello, who once worked at the hospital was reportedly forced to quit after only six months on the job because of a sexual harassment allegation levelled against him.
Maureen Kwankam, a doctor at the hospital, told New York Daily News that he promised to return and “kill” everyone when he was “fired” in 2015.
“We fired him because he was kind of crazy. He promised to come back and kill us then,” said Kwankam.
Bill de Blasio, mayor of New York, described the attack as a “horrific situation in the middle of a place that people associate with care and comfort”.
“We’ve had a real tragedy here in the Bronx this afternoon. It’s something we’ve seen around the country, and now we’ve experienced it here.”
According to the New York Times, Bello was arrested in August 2004 after a 23-year-old woman accused him of sexual harassment.
He was subsequently charged with sex abuse and unlawful imprisonment.
Bello was said to have pleaded guilty to unlawful imprisonment in the second degree and was sentenced to community service.
