The Central bureau of Investigation on Monday 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 on Sunday 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
