A PHILADELPHIA police officer who was caught allegedly driving drunk on duty in a marked patrol car this weekend previously had been dismissed from the force for an alleged assault, according to police.

Darryl Cathey, a six-year veteran who was assigned to the 12th District at 65th Street and Woodland Avenue in Southwest Philadelphia, was charged with driving under the influence, aggravated assault and related offenses in connection with the Saturday-morning incident.

According to authorities, about 12:10 a.m. a police supervisor found Cathey, who was supposed to be on duty, in a marked patrol car with three flat tires parked outside the 12th District.

The supervisor said that Cathey, 26, had bloodshot eyes and smelled of booze and that when questioned, Cathey had no idea the cruiser had three flat tires and that he'd been driving on its rims, police said.

When the supervisor tried to place Cathey in custody, Cathey allegedly put up a fight, resulting in additional charges of aggravated and simple assault.

Commissioner Charles Ramsey suspended Cathey for 30 days with the intent to dismiss - something he already has done once before.

According to previous reports in the Daily News, in 2011, Cathey, who then had just two years on the force, was arrested for allegedly beating up his ex-girlfriend.

He was charged with robbery, terroristic threats, simple assault and related offenses and was suspended for 30 days with the intent to dismiss.

However, when the case went to court, Cathey's ex failed to appear to testify - four times. Prosecutors were forced to withdraw the charges, and Cathey got his job back.
