The attack on a Nigerian prison by Islamist sect Boko Haram, which freed 721 convicts, resulted in the death of five people on Tuesday.
The state commissioner of police, Danlami Yar’Adua, confirmed that a soldier, a policeman, two prison warders and a civilian were killed during the gunbattle involving 200 members of Boko Haram.
It has also been confirmed that at least 35 of the inmates who were set free have been re-arrested by police in Bauchi.
Police suspect the prison was attacked because it was holding 80 members of the religious group.
Boko Haram has been at odds with Nigerian officials because the group wants the government to impose Islamic law, known as sharia, in the entire Muslim-dominated northern half of Nigeria.
