PHILADELPHIA (CBS/AP) — A Philadelphia police officer will be fired after he was arrested Thursday on robbery and assault charges. The district attorney’s office said Officer Luis Miranda, 40, Gregorio Esquilin, 56, and Juan Luis Esquilin, 32, face charges for the December 2017 incident in which 15 people were robbed, threatened or assaulted.

Philadelphia Police issued a statement that said Miranda was arrested at about noon Thursday and was put on a month’s suspension with the agency intending to fire him.

All three men are accused of robbery, aggravated assault, terroristic threats and other offenses. The Esquilins are father and son. Online court records do not indicate if any of the three men are represented by lawyers.

Police Commissioner Danielle Outlaw calls the charges against Miranda disturbing and disheartening.
