Hyderabad, Aug 21 - There is enough material for successful prosecution in the Rs.78-billion Satyam fraud case and as soon as the Andhra Pradesh High Court sets up a fast track court there will be further progress in the matter, the government said Friday.

'As far as the CBI (Central Bureau of Investigation) and the ministry of corporate affairs are concerned, the investigations are more or less over. There may be some minor things still to be done,' Minister of State for Corporate Affairs Salman Khursheed said.

Speaking to reporters on the sidelines of a conference here, Khursheed said an additional charge sheet would be filed as the trial court has granted permission for it.

'We have permission to file an additional charge sheet based on information available during the last few weeks,' Khursheed said, adding: 'We have got enough material for prosecution and that's why charge sheet is filed.'

When his attention was drawn to attempts of the accused to avoid lie-detector test, the minister said: 'These are matters of legal procedure.'

'The CBI is obviously in good hands. We have an outstanding legal team looking after it. Whatever is required will be done,' Khursheed said.

'The Enforcement Directorate (ED) and IRS (Internal Revenue Services) are still looking into some leads. We need to hear from them before we can make an assessment of the approximate figures of the amount involved. Obviously it was pretty huge,' he said.

The ED and IRS are also looking into diversion of Satyam funds. The ED is looking into two Maytas firms as well to understand whether their relation with Satyam required any investigation, the minister said.
