"S Ravindran has committed suicide only after intimidation crossed all limits," Vaiko said.
Stating that US and European nations treated Tamil refugees with respect, he alleged, "It is only in Tamil Nadu that they are treated like extremists and terrorists and threatened and intimidated."
S Ravindran, who lived at the Uchampatti refugee camp in Madurai district, committed suicide yesterday by holding an electric overhead cable after climbing a high-rise power transmission tower.
Demanding appropriate action against the official, Vaiko alleged that the incident had brought bad reputation for Tamil Nadu and demanded solatium for Ravindran's kin.
Stressing that refugees should be treated with respect, Ramadoss alleged, "Inhumane approach of Tamil Nadu's rulers and some officials" was the reason for the suicide.
Stating that camp occupants were "unable to bear the harassment," he said only due to such factors some of them undertake dangerous boat trips to countries like Australia and end up getting killed.
