India on Monday blacklisted six armament firms for 10 years for their alleged role in a 2009 weapons bribery scandal, a government statement said.
The firms targeted by the defence ministry included Singapore Technologies Kinetics Ltd, Switzerland's Rheinmetall Air Defence, Israeli Military Industries Ltd and Russia's Corporation Defence (CDR), the statement said.
"The firms were recommended for blacklisting by the Central Bureau of Investigation on the basis of evidence collected against them," the statement by the defence ministry said.
The two other companies blacklisted were both Indian firms -- RK Machine Tools Ltd and TS Kisan and Co Private Ltd, the statement faxed to AFP said.
No comment was immediately available from the companies named in the statement, which said those blacklisted cannot do business with the Ministry of Defence "for a period of 10 years".
India froze deals worth $1.5 billion in 2009 with seven companies after police arrested a top defence ministry bureaucrat on charges he allegedly accepted bribes from the firms.
The firms were issued notices to show why action should not be taken against them in relation to the bribery case, the statement said.
"The decision to debar (the companies) was taken today after taking into consideration their replies," the statement said.
Indian defence procurement has traditionally been an opaque business, marred by postponements, and repeated re-negotiations over cost and scandals.
An artillery bribery scandal in 1986 involving then Swedish firm Bofors AB led to the downfall of the government of then prime minister Rajiv Gandhi.
