According to sources in the Ministry of Corporate Affairs preliminary investigation into the Rs 7,800-crore fraud in the Hyderabad-based IT firm suggests a violation of insider trading norms under the Companies Act.

RoC's report said violations may have occurred under sections 372A, 205A, 297, 299, 300 and 207 of the companies law.

The report also said there may have been window-dressing of published financial statements with an intention to allure investors, resulting in false value of shares appreciating in the stock exchanges.
