The CBI, yesterday asked the Vectra Group chairman Ravi Rishi not to leave the country.

The army chief has sent a written complaint to the CBI but the agency has asked him for more details. Rishi and the UK-based Vectra Group are also being investigated in the Czech Republic following a complaint last year from an activist of corruption watchdog Transparency International that they had caused losses to Tatra, reports the Telegraph.

Documents show that the Vectra Group, which has substantial stakes in Tatra a.s. in the Czech Republic and in Tatra Slovakia in Slovakia, tried to retain its near-monopoly over the supply of heavy vehicles to the Indian Army by practically bidding twice for the same contract.
