The Central Investigation of Bureau (CBI) is likely to file a closure report on the death of Sadiq Batcha, one of the accused in 2G spectrum scam who committed suicide last year.

Sadiq Batcha, a close aid of jailed former Telecom Minister A Raja and owner of Greenhouse Promoters, was found hanging from the ceiling on March 16 at his Chennai residence.

The All India Institute of Medical Sciences (AIIMS) has confirmed it as suicide, said the CBI.  The AIIMS was roped in to examine the forensic and post-mortem report of Batcha.

The CBI also said that it was quite satisfied with the findings of the Chennai police department into the Batcha case.

Initial reports claimed it was a suicide. However, Batcha's death sparked speculations over his decision to kill himself while multi-agency investigation was on.

The investigators speculated whether Batcha was forced by outsiders to take the extreme step.

However, after almost a year-long probe into this suicide case to find if there was any external pressure that led to Batcha's death, the CBI apparently failed to detect any evidence proving this speculation.  

Batch's wife claimed that he committed suicide as he was "unable to cope with pressure" of multiple agencies probing him. The CBI officials and Enforcement Directorate (ED) made a few raids at Batcha's house over his possible involvement in the 2G scam before he was found death.  

The Supreme Court allowed the CBI to carry out a probe into the suspicious death of a 2G scam accused as Batcha was suspected of knowing inside information related to the telecom scam.

Batcha and his Green House Promoters firm came under the scanner after probing agency indicted his alleged role in 2G spectrum scam.

The Green House Promoters allegedly acted as a front company for Raja in receiving bribe money from telecom companies, which were benefited from the 2G scam.
