They are 16 and 17 years old.
According to Knight, the teens were "acting up" inside a cell and when a guard approached the cell to try and calm down, one of them grabbed the guard's arm and tried to pull it through the cell's bars.
Another inmate allegedly twisted the guard's arm allowing the group to overtake the guard.
The sheriff said the inmates stole the guard's keys, let themselves out and fled the jail.
The guard received minor injuries but is expected to be okay.
After a manhunt by ground and air, authorities found five of the inmates and took them back to jail. Within an hour, the sixth inmate was picked up and taken back just before 4 a.m. Monday.
This isn't the first time inmates escaped from the Edgecombe County Jail.
In April there were two separate incidents involving four inmates. In both cases, the inmates were recaptured in less than one day. However, three suspects managed to make it to West Virginia before they were caught.
Since those escapes, Knight said the jail added barbed wire, an alarm system and better monitoring equipment. The sheriff hasn't released the names of the inmates. They face counts of escaping, kidnapping and assaulting an officer.
