(NEW YORK POST) As cops were being threatened and assaulted and the city reeled over the execution of two officers, Mayor Bill de Blasio prayed at St. Patrick’s Cathedral Sunday — then went into hiding.

Police Commissioner Bill Bratton visited the scene of the horrific attack in Brooklyn and Gov. Andrew Cuomo paid a wrenching condolence call at the home of one of the slain cops, but de Blasio ran from reporters and was nowhere to be found after the church service.

He showed up for 10:15 a.m. Mass with his wife, Chirlane McCray, and Bratton, with all three sitting in a front-row pew as Cardinal Timothy Dolan urged prayers for the slain cops’ families, the NYPD — and the embattled mayor.
