New Delhi: The Central Bureau of Investigation (CBI) said on Tuesday that it had filed a closure report in a case pertaining to the purchase of trucks for the Indian army.

The case, which was registered in 2012, involved government owned defence company Beml Ltd and Tatra Vectra Motors Ltd, a joint venture between the UK-based Vectra group and Czech firm Tatra Trucks.

The CBI closed the case on the grounds of insufficient prosecutable evidence, a spokesperson for the agency said.

A CBI official said the allegation that trucks were supplied by Tatra Sipox UK did not stand during the probe as the Czech-based company had submitted in writing that it was an authorised distributor of its products.

The allegation that initial payment mode was in dollars but later converted to euros, thus increasing the cost, also failed to stand legal scrutiny after the Bank of Czechoslovakia claimed that it was the bank that had insisted on the change in currency, the official said.

CBI also concluded that lack of indigenisation of trucks supplied by Tatra was not a lapse.

The latest closure report comes even as the agency on 15 July had chargesheeted retired lieutenant general Tejinder Singh for his alleged involvement in irregularities in the proposed purchase of trucks.

In its chargesheet, the CBI has said that there is “circumstantial evidence" that Tejinder Singh had in September 2010 “offered to bribe" then army chief V.K. Singh, who is now a minister in the Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA) government.
