Federal prosecutors in New York City say a man who was the top U.S. representative of outlawed LTTE deserves a stiff prison sentence.

Karunakaran Kandasamy faces a maximum 20-year term at sentencing on Friday.

In 2009, four Arms Procurement Agents of the LTTE in US including Kandasamy pleaded guilty to conspiracy to provide material support to the LTTE, a designated foreign terrorist organization in the United States.

Among the charges against them were involvement in the purchase of sophisticated weaponry such as missiles, machine guns, artillery, radar and other equipment for the LTTE and attempts to bribe purported U.S. State Department officials to remove the LTTE from the list of designated foreign terrorist organizations ban in the United States.

Karunakaran Kandasamy was the director of the American branch of the LTTE and oversaw and directed the LTTE's various activities in the United States, including raising millions of dollars for the LTTE and laundering it through the Tamil Rehabilitation Organization.
