Nine months after the mysterious death of South Indian actor Kalabhavan Mani, 45, the Special Investigations Team (SIT) received the polygraph test results of his six close aides. But the tests failed to provide any new clue into the death of the actor, who passed away on 8 March this year. 


Mani's aides, including his manager and driver, had undergone polygraph tests. But reports quoting police sources say that his aides adhered to their earlier earlier version of events and the tests did not find anything unnatural. 


Earlier the analysis at the Central Forensic Science Laboratory in Hyderabad had found high level of methyl alcohol in Mani's blood samples that led to the suspicions that spurious liquor could have caused his death. But the statements of his aide did not reveal that could substantiate that assumption. 


 Mani’s brother RLV Ramakrishnan had alleged 'foul play' in the actor's death and had raised allegations against the actor's close friends and aides. 

The SIT, in a bid to find out the reason behind the presence of methyl alcohol in Mani's body, had hopes that polygraph tests of his aides who were with him on the night before his death, could throw some light on the mystery.  The Hyderabad lab tests were in contrast to the report of the forensic lab at Kochi that indicated the presence of chlorpyrifos, a toxic pesticide in Mani's viscera sample. The confusion in lab reports and the statements of his friends that they did not have liquor during their meeting with Mani at his farm house in Chalakkudy a day before his death had deepened the mystery in the case. 


The 45-year-old actor, who played in versatile roles in South Indian films, was found in a serious condition at his farmhouse at Chalakudy on 5 March this year. Though he was rushed to Amrita Institute of Medical Sciences, he breathed his last next day.

On 11 June, Mani's family met Chief Minister Pinarayi Vijayan and demanded a CBI enquiry into the death.
