Top staff shakeups are par for the course under a new police commissioner, but the storm of resignations and reassignments at the NYPD over the past three days — including Chief of Department Jeffrey Maddrey stepping down amid bombshell sexual misconduct allegations — served as a shock to the system with the head of the Internal Affairs Bureau the latest high-ranking cop to get the ax.

On Saturday, New York City Police Commissioner Jessica S. Tisch immediately appointed Edward A. Thompson as Interim Chief of Internal Affairs. A spokesperson for the New York City Police Department told PIX11 News.

The shake-ups among top NYPD leadership continued Saturday as Commissioner Jessica Tisch removed the head of the department’s Internal Affairs Bureau. The ousting of Chief of Internal Affairs Miguel Iglesias came just one day after Chief of Department Jeffrey Maddrey submitted his resignation before being accused of trading substantial overtime approvals for sexual favors.
