CLEVELAND (AP) — Four guards from a troubled and overcrowded county jail in Cleveland have pleaded not guilty to charges that include civil rights violations.

A former guard and three current ones pleaded not guilty Wednesday in Cuyahoga County Common Pleas Court to charges related to three separate incidents since July inside the Cuyahoga County Corrections Center. The not-guilty pleas were entered via video from the same jail where the men are accused of committing the violations.

The judge on Wednesday set bond for each man at $5,000.

The jail in downtown Cleveland has been under scrutiny since the deaths of seven prisoners over a four-month period last year.

A report by the U.S. Marshals Service called conditions at the jail "inhumane" and unsafe.
