The NYPD has agreed to send auxiliary police officers to patrol the subways. This comes after heated arguments between the MTA and the city over crime underground.

The MTA has been sounding the alarm for months about the need for more police in the subways. They say assaults on workers and customers are higher than last year. Just this week an off duty transit worker was slashed with a box cutter and is in critical condition. Another was knocked unconscious.

The mayor has accused the MTA of fear mongering, saying the subways have never been safer.

Major crimes are down, but that's largely because there are fewer thefts.

Nonetheless, the NYPD agreed to send volunteer officers to patrol the 20 busiest stations.

The MTA says that's a good step, but it still wants more armed police and mental health resources for the subways.
