The freed man, Serdar Senel Suroglu, 33, gave his official testimony to military authorities but did not reveal details of his ordeal to the press.

"I am just happy that the nightmare is over," he was quoted as saying by the agency.

Suroglu was abucted on September 24 in the eastern province of Tunceli by suspected militants from the Kurdistan Workers' Party (PKK).

Officials had said at the time that they thought Suroglu, the son of AKP Tunceli chairman Veli Suroglu, was kidnapped in a bid to extort money from his family.

The PKK, blacklisted as a "terrorist" group by Ankara and much of the international community, has fought for self-rule in Turkey's mainly Kurdish eastern and southeastern provinces since 1984.

The conflict has claimed more than 37,000 lives.

The rebels, who have bases in neighbouring northern Iraq, ordered a unilateral ceasefire from October 1, saying they hoped this would pave the way for a dialogue to resolve the conflict.
