The Central bureau of Investigation yesterday questioned Vectra Group Chief Ravi Rishi in connection with a case of alleged irregularities in purchase of Tatra trucks for the Indian Army. Mr. Rishi, who owns the Vectra group and has a majority stake in the Tatra trucks, was earlier grilled by the premier probe agency on Saturday in connection with the Tatra trucks deal case.

The CBI was issued a lookout notice against Mr. Rishi, a British citizen, to prevent him from leaving the country. The probe agency has alerted all airports and exit points to ensure that he does not leave the country.
