The parents of dalit youth Ilavarasan, whose death continues to remain shrouded in mystery, on Saturday refused to accept the police version that he committed suicide and demanded a probe by CBI or a Special Investigation Team.
Expressing suspicion over the cause of death of their son, whose body was found along railway track in Dharmapuri, Ilavarasan's parents-- T Elango and Krishnaveni, accompanied by their advocates, told reporters here that police had not investigated the various angles in the case.
They alleged that selective leaks to media were being made to show that the death was a suicide.
Elango alleged that they were lapses in the police investigation as they did not span out to nearby areas for clues and did not deploy sniffer dogs.
He also expressed doubts over police verifying the authenticity of a letter purportedly written by his son and their declaration that it was a case of suicide without referring to forensic tests.
Ilavarasan's marriage with an upper caste girl Divya in October last year triggered caste clashes in parts of Dharmapuri and the girl later chose to live with her mother as her father committed suicide over her tying the knot with a dalit boy.
