COLOMBO, Sri Lanka, Feb. 25 (UPI) -- Visvalingam Gobithas, a British citizen of Tamil origin, was found dead Monday at Welikada Prison in Colombo, Sri Lanka.
Gobithas, 43, was detained in 2007 by Sri Lankan authorities under the nation's Prevention of Terrorism Act. Authorities accused him of financially backing the Tamil Tigers, a separatist militant organization, which Gobithas denied. He was finally convicted in 2012 after being held without charge for five years.
