Chennai: Doctor V Dekal, who conducted autopsy on the body of Sadiq Batcha, has resigned saying it had nothing to do with the case as he plans to contest elections.

Though reports of his resignation came days after the death of Batcha, former Telecom Minister A Raja’s aide, Dr V Dekal said he had put in his papers in the first week of March as he had intended to contest the April 13 Tamil Nadu Assembly elections.

"I resigned because I wanted to contest the elections as an independent. This is in no way related to the case," he said.

Dr Dekal said he was yet to make up his mind to contest the polls since his relieving orders were yet to come and he had put in the papers after elections were announced. He planned to contest as an independent.

After performing the autopsy, Dekal had said Batcha's death was due to asphyxia and his body showed compression of the neck with hanging mark. "We cannot say now whether it was suicide or murder, the report would be available in two weeks," he had said.

The 38-year-old Batcha, who was the Managing Director of Greenhouse Promoters, a firm under the scanner of the CBI as well as the Enforcement Directorate in connection with the 2G spectrum scam, was found hanging in his house at Teynampet in South Chennai by his wife Rekha Banu and his driver.

His wife claimed that he took the step as he was "unable to cope with the pressure" of the probe.

Batcha, whose official and residential premises were raided by CBI and questioned at least four times in the last two months, had left a suicide note in which he had stated that he was "embarrassed" by the raids and the extensive media coverage of them.
