Late Libyan leader Muammar Gaddafi's son Hannibal has been freed after being briefly kidnapped by an armed group in Lebanon, security sources said on Saturday.
In a video shown on Lebanese TV, the captive businessman was seen appealing for more information concerning the 1978 disappearance of the prominent Lebanese Shia cleric Musa al-Sadr, BBC reported.
The 40-year-old former playboy was given sanctuary in Oman in 2012.
His father Muammar was overthrown by rebels in a 2011 uprising.
Al-Sadr, one of the most prominent Shia clerics of the 20th Century, disappeared along with two others during a trip to Libya in 1978.
Muammar Gaddafi denied any involvement in his disappearance, but many suspect him of having orchestrated it.
