City Comptroller Scott Stringer is delaying his approval of the NYPD's Body Camera contract with an outside company because he still has questions about the deal.

The city's plan to outfit all patrol officers with cameras by the end of the 2019 cannot go forward unless the comptroller signs off on the agreement company called Vievu.

"We are seeking additional information on this contract from the NYPD and it will not be registered at the current time," a spokesman for Stringer said. "We are working with the City to gain more clarity."

A spokesman for the mayor called the bidding process for the cameras, "one of the most rigorous and extensive in recent City memory," adding, "it is baffling that anybody would stand in the way of greater transparency and the deployment of these important policing tools. The comptroller will not slow down our commitment to equip all patrol officers by 2019."
