Chennai: Chennai-based realtor Sadhick Batcha, a close aide of jailed former telecom minister A Raja, was declared dead after he was found hanged at his home on Wednesday, police said. There was no immediate clarity on whether the death was a suicide.

Batcha’s body was brought to the Royapettah government morgue in Chennai from Apollo Hospital in an ambulance at around 3:20 pm.

The Central Bureau of Investigation (CBI) was allegedly probing Batcha over his involvement in the allocation of second-generation (2G) telecom spectrum. Raja is currently in custody for his alleged role over the 2008 allotment of frequencies.

CBI has denied putting pressure on Batcha. While, calling his demise unexpected, it said the event would not affect the investigations.

CBI told the Supreme Court earlier on Wednesday that it would file the main chargesheet in the 2G spectrum case against Raja and two companies before 31 March. It said “this is the beginning" and many supplementary chargesheets will be filed later.

A month ago, CBI had questioned Batcha, promoter of Chennai-based realty firm Green House Promoters Pvt. Ltd, and Mahendra Nahata of Himachal Futuristic Communications Ltd.

At that time, a senior CBI official who didn’t want to be named had said that a previous raid yielded “incriminating documents." Batcha’s “meteoric rise" in recent years had brought him under the scanner, the same official had said.

The official added that CBI also found a link between him and Shahid Balwa, promoter of Swan Telecom Pvt. Ltd (now known as Etisalat DB Telecom India Pvt. Ltd). According to CBI, Balwa, who is also in custody, colluded with Raja. Balwa has denied all the allegations.

A November 2010 report of the Comptroller and Auditor General of India showed that the pan-India 2G licences offered to nine firms for Rs1,658 crore had caused a revenue loss of up to Rs1.76 lakh crore.
