A former Philadelphia police officer who was fired after being filmed pepper-spraying protesters as they knelt on an interstate during a Black Lives Matter demonstration last month now faces criminal charges.

Richard Paul Nicoletti, 35, faces six misdemeanor charges of simple assault, reckless endangerment, official oppression, and possession of an instrument of crime, the district attorneys office announced Wednesday.

The charges follow a June 1 video showing Nicoletti, then assigned to the police departments SWAT unit, walking up to people kneeling along Interstate 676 and without provocation spraying the three of them in their faces, according to the DAs office.
