TRIPOLI - Large amounts of cash and gold have been reportedly discovered on Tuesday in the office of Seif al- Islam, the second son of Libya's fallen leader Muammar Gaddafi, in the capital of Tripoli.

A fighter belonging to the ruling National Transitional Council (NTC) told Xinhua that the cash and gold, which may worth " millions," were found in Seif al-Islam's abandoned office near the Bab al-Aziziya military compound in southern Tripoli.

Part of the bounding wall and several buildings of the massive compound, which has for decades housed Gaddafi, his families and major aides, have been demolished since Sunday by the NTC members, who aim to delete all the traces of Gaddafi's 42-year-old rule.

However, the fighter, who asked to remain anonymous, said some of the cash and gold are yet to be taken out from underground the building.

Sources were quoted as saying shortly after Tripoli fell into the hand of the NTC that large amounts of money were kept in the house of Seif al-Islam, an important figure in the North African country even though he held no major positions.

Seif al-Islam was believed to have been holed up in Bani Walid, a desert oasis town now mostly controlled by the NTC. But he is not captured yet. Meanwhile, his brother Mutassim and Gaddafi himself are also at large.
