The New York City Police Department confirmed that it would send officers near some news media offices Wednesday morning.
The news comes after a reporter and cameraman were shot and killed while on assignment and on live television in Virginia.
A spokewoman for the NYPD said it already deployed police units to "various media outlets."
By the late morning, state officials in Virginia told reporters suggested that the suspect might be a former coworker.
"Law enforcement personnel have a photo of the suspect," Virginia Gov. Terry McAuliffe said on a radio program hours after the shooting. "We believe it's a disgruntled employee of the station, and they're in pursuit."
Reporter Alison Parker, 24, and cameraman Adam Ward, 27, both died after they were reporting live at around 6:45 a.m.
