The Indonesian government says a new commission to investigate alleged corruption by former President Suharto could call for him to be placed under house arrest or banned from foreign travel.

The official Indonesian news agency Antara quoted the attorney-general, Muhammad Ghalib, as saying such demands could be made if Mr Suharto obstructed the inquiry.

His remarks came the day after a senior official of the ruling Golkar party, Marzuki Darusman, called for the former president to be placed under house arrest.

Meanwhile, one of Mr Suharto's sons, Hutomo "Tommy" Mandala Putra, has been questioned by the attorney-general's office for several hours over corruption allegations against a company he partly owns.

A full investigation into allegations against Mr Suharto, his relatives and business associates has been one of the key demands of Indonesian students demonstrating for political reform.
