One of seven prison guards charged with sexually abusing female inmates at a jail in Scranton has pleaded no contest to a count of official oppression.

George Efthimiou, 51, was charged for having sex on multiple occasions with a Lackawanna County Prison inmate while she was on house arrest.

When the woman told Efthimiou she wanted to stop having sex with him, he threatened to have her house arrest revoked but never carried out his threat, prosecutors said.

Efthimiou is awaiting sentencing. He is the second former Lackawanna County Prison guard to enter a plea in what Attorney General Josh Shapiro said was a pervasive culture of institutional abuse over many years.

Jeffrey Staff pleaded no contest to a count of official oppression last month and was sentenced to nine months of probation. Staff additionally is barred from ever seeking employment in a correctional facility or in law enforcement.
