In January 2006 it was discovered that the CBI had quietly unfrozen bank accounts belonging to Italian businessman Ottavio Quattrocchi, one of those accused in the 1986 Bofors scandal which tainted the government of Rajiv Gandhi. The CBI was responsible for the inquiry into the Bofors case. Associates of then-prime minister Rajiv Gandhi were linked to alleged payoffs made during the mid-1980s by Swedish arms firm AB Bofors, with US million in kickbacks moved from Britain and Panama to secret Swiss banks. The 410 howitzers purchased in the US million arms sale were reported to be inferior to those offered by a French competitor.
