Ali Haider Gilani, son of ex-premier Gilani, has been recovered from Afghanistan's Ghazni province, Pakistan's Foreign Office said in a statement.
Six suspects, including two women, were arrested Thursday during an operation to trace the kidnapped son of former premier Yousuf Raza Gilani in Pakistan's restive northwest, officials said.
Former premier Yousuf Raza Gilani's son Ali Haider, kidnapped by gunmen while campaigning for Pakistan's landmark elections, had received threats from the banned Lashkar-e-Jhangvi and Sipah-e-Sahaba.
Former premier Yousuf Raza Gilani's son Ali Haider was on Thursday abducted by suspected militants who shot and killed two persons in Punjab province, triggering fresh concerns about Pakistan's general elections that have already been badly hit by Taliban violence.
Haider's release was the second successful instance of a dramatic rescue in a high-profile kidnapping case after slain Punjab governor Salman Taseer's son Shahbaz, who was abducted in 2011, was found in March after spending nearly five years in captivity.
With the Pakistani police yet to make any breakthrough in their efforts, former prime minister Yousuf Raza Gilani on Friday sought the help of the Inter-Services Intelligence to locate his son Ali Haider, who was kidnapped by heavily-armed men in Multan.
Pakistan's former prime minister Yousuf Raza Gilani on Sunday said he had spoken to his son Ali Haider for the first time since he was kidnapped by a Taliban group in 2013 and is now being held in Afghanistan.
Police in Pakistan have busted an illegal telephone gateway exchange in Lahore, allegedly being operated by the Taliban to make ransom calls to families of persons kidnapped by them, including the sons of former premier Yusuf Raza Gilani and slain Punjab governor Salman Taseer.
Pakistani authorities claimed to have foiled a plot to target Prime Minister Nawaz Sharif by busting a terror network planning to launch suicide attack on his residence in Raiwind on the outskirts of Lahore.
Awais Ali Shah, a lawyer himself, was abducted last month from Karachi. He was found in Tank.
