Sesa Goa, an Indian unit of the Britain-based metals and minerals giant Vedanta group, Thursday said the company and its subsidiary Sesa Industries were being investigated by the Serious Frauds Investigation Office for malpractices, financial and other irregularities.

The SFIO, at the instructions of the ministry of corporate affairs, initiated the enquiry after one of the shareholders of Sesa Industries lodged a complaint against the company with the registrar of companies, who in turn recommended such an investigation.
