Officials in New Orleans, Louisiana, USA are calling on an inmate to turn himself in after a clerical error led him to be mistakenly released from the same prison where 10 men escaped earlier this year, NBC News reports.

Khalil Bryan was mistakenly released from the Orleans Parish Justice Center by the sheriff’s office, an apologetic New Orleans Police Superintendent Anne Kirkpatrick said at a news conference.

Also at the news conference, Orleans Parish Sheriff Susan Hutson made “a sincere apology to the people of New Orleans” and took “full responsibility” for Bryan’s mistaken release. Bryan was released after a clerical error caused officials to confuse him with another inmate with a similar last name, Hutson said.

“While our systems are designed to catch these discrepancies, human error led to a breakdown in the verification process,” Hutson said. Officials in the area have launched an investigation and are actively searching for Bryan. Hutson said those who were on duty during Bryan’s release will be called in for questioning, as this was a human error.

Bryan is serving time for charges including possession of stolen property, possession of drug paraphernalia and resisting an officer, Kirkpatrick said, noting the inmate’s “violent criminal history.” Hutson later added that he was charged with home invasion, aggravated assault and domestic abuse.
