Police in NYC Ramp Up Security After Manchester Blast Kills More Than a Dozen

Police increased security at tourist hot-spots and other heavily-trafficked areas of New York City after an explosion outside an Ariana Grande concert killed nearly two dozen people and injured scores more at an arena in Britain on Monday, senior law enforcement officials told News 4.

At least 22 people were killed and dozens more were hurt after an explosion outside Manchester Arena following an Ariana Grande concert, officials say. Katherine Creag reports.

Gov. Cuomo said that state law enforcement officers will step up security and patrols in response.
