In the incident, six inmates, including Islamic militants, escaped from the prison after they overpowered one of the guards and grabbed his weapon. The prosecutors late on Sunday ordered that the 14 policemen, who include three officers, be held in custody pending further investigation. They face charges of negligence and complicity in the jailbreak. During their escape, the inmates killed a police major who tried to apprehend them and wounded another policeman and a passer-by. The Interior Ministry, which runs the police, has launched an independent investigation into Thursday's incident.
