A dozen of Taliban detainees have been released from Kandahar prison on faked letter, a local newspaper reported on Monday.

"Twelve high profile Taliban inmates have mistakenly been freed from the central jail in Kandahar with falsified documents," citing police, the English paper Daily Outlook writes in its Monday edition.

Quoting deputy police chief of Kandahar, Rahmatullah Atrafi, the newspaper added that a letter from the Attorney's office had ordered the release of 16 prisoners who had their jail terms served but later it appeared that the later bore fake signature of the Attorney.

A local official in Kandahar on the condition of anonymity confirmed the release of the inmates and told Xinhua that the wardens of the jail, after receiving a fake letter claiming to be from the national intelligence agency, set free 12 detainees on Saturday.

It is not the first time that Taliban detainees made their escape from Kandahar prison. Previously in 2008 and 2011 more than 1,500 Taliban detainees had made their good escapes from Kandahar central jail respectively.
