New Delhi, July 20 (IANS): The BJP on Monday demanded a CBI investigation into the payment of $976,630 in bribes allegedly to the then minister and officials in Goa by New Jersey-based consultancy firm Louis Berger's top officials.

"We demand a full-scale CBI inquiry into how much more money was paid and to whom," Bharatiya Janata Party spokesperson M.J. Akbar said at a press conference here.

"This is only the proverbial tip of the iceberg. And since the Congress is involved, we would like to know how much of this (money) was shared with the ruling family of Delhi," he added.

"In this case, the finger points directly to Digambar Kamat, the former finance minister during the Congress rule in Goa," Akbar alleged.

Louis Berger's top officials have already pleaded guilty to offering bribes to the tune of $3.9 million to secure contracts in Asian countries like India, Vietnam, Indonesia and Kuwait.

While the settlement announced by the Justice Department did not identify politicians and officials offered the bribes, the documents revealed that $976,630 in bribes was paid during 2009-2010 to then minister and other officials in Goa.

The consultancy firm was part of a consortium that eventually won a contract to execute a water and sewerage project in Goa.
