Two people killed in stabbings in New York City at three different locations in Manhattan

A lone, knife-wielding assailant killed two men and seriously injured a woman Monday morning during an hours-long stabbing spree through the streets of New York City, authorities said.

The two slain men, attacked near 444 W. 19th St. at 8:22 a.m. ET and then at 10:27 a.m. near 500 E. 30th St., were both taken to Bellevue Hospital before being pronounced dead, officials said.

Then, at 10:55 a.m., a woman was stabbed in the shadow of the United Nations, near East 42nd Street and First Avenue, leaving her in critical condition.

A “person of interest” was arrested a short time later at 46th and First, said police, who are not looking for anyone else in connection with these stabbings.

“At this point, these attacks appear to be unprovoked, that he simply walked up to them and started attacking them with the knives,” NYPD Chief of Detectives Joseph Kenny told reporters.
