The NYPD and the mayor's office are debuting a new tool they say will help keep New Yorkers safe on the subway.

K5, the new security robot, is planned to serve as a crime deterrent on a two-month trial run. The device will only monitor the Times Square station between midnight and 6 a.m.

For the first two weeks, Mayor Eric Adams says it will be trained to map out the station but will not be on the platform. The device will record video that can be reviewed in case of an emergency but will not record audio, according to officials.

MTA officials say overall crime in the subway system is down compared to 2022.
