NEW YORK (AP) — New York City officials say some 6,000 police will be on duty tonight during the New Year’s Eve celebration in Times Square.

People usually begin filling the square and adjoining blocks before sundown, and everyone arriving will be screened for weapons with a metal-detecting wand.

Tonight’s party begins with musical performances, including Luke Bryan, Demi Lovato and Carrie Underwood, and ends with fireworks and the descent of a glittering crystal ball from a rooftop flagpole.
