NY1 Criminal Justice Reporter Dean Meminger has learned exclusively that NYPD Chief of Department James O'Neill is ordering an immediate review of how officers on modified duty receive overtime pay.

This comes after revelations that Officer Daniel Pantaleo has earned approximately $40,000 in pay over the last two years in addition to his base salary, which was $76,488 in fiscal year 2014 and rose to $78,026 in fiscal year 2016.

Pantaleo has been on modified duty since July 2014, when he was captured on cellphone video putting Eric Garner in an illegal chokehold, in an arrest that caused Garner's death. 

Pantaleo's overtime earnings were first reported by Politico New York.
