New Delhi, Apr 3 (IANS): The Central Bureau of Investigation (CBI) Monday questioned the owner of Britain-based Vectra group Ravi Rishi for four hours in connection with alleged irregularities in the supply of Tatra trucks to the Indian Army.

The CBI questioned Rishi, named as an accused in the agency's FIR, for the second time in the case.

"There is no arrest so far in the case," said a CBI official.

The CBI raided Tatra offices in Bangalore and New Delhi on Friday.

Rishi has termed the allegations against him as unfortunate, saying the trucks were sold through public sector undertaking BEML.

He also said the charges levelled with regard to Tatra trucks by Army Chief Gen V.K. Singh were baseless.

The move comes after the army chief alleged that Lt. Gen. (retd) Tejinder Singh had offered him a bribe of Rs.14 crore for clearing a consignment of "sub-standard" trucks.

The name of Tatra and BEML was taken by the army in a press release issued by it on March 5, alleging that Tejinder Singh had offered a bribe on behalf of Tatra and Vectra Ltd.

Rishi had earlier said that he is not related to Tejinder Singh. He also said that the trucks were sold in parts to BEML which made the completed trucks and sent it over to the Army, and that this has been happening since 1986.

The CBI on Friday registered a case in connection with the supply of all-terrain Tatra trucks and called for questioning Vectra group chairman Ravi Rishi who is a majority stake holder in Tatra.
