Raveendran (48) requested a retired Revenue Inspector, who had gone there to take a roll call, that his son has been hospitalised and not be marked "absent" as he would not be able to get refugee rations for him, the officials said.
Despite his plea and producing the medical chit as proof, the official allegedly marked his son 'absent', they said.
Ravindran then climbed a nearby high tension tower and electrocuted himself by touching a wire, they said, adding the other refugees then allegedly thrashed the retired official.
The refugees later staged a demonstration, demanding action against official responsible for the suicide of the man.
Meanwhile, leader of fringe Tamil outfit Tamizhar Peravai P Nedumaran demanded a probe into the death of the refugee and that some relief be given to his family.
He also demanded that action must be taken against the officials who "harass" refugees in the camp by conducting frequent inspections.
