A copy of the suicide note allegedly written by Sadiq Batcha has been sent to the forensic science laboratory for confirming his handwriting, police said. Batcha, a close aide of the former Telecom Minister, A. Raja, committed suicide by hanging at his house here on March 16, according to the police.
“We have taken samples of Batcha's handwriting from a book. His brother-in-law handed over a suicide note dated March 15 to the police. The dress he wore at the time of committing suicide had some brown stains. The clothes have also been sent for analysis,” a police official said.
The State government announced that the case would be transferred to the Central Bureau of Investigation, but the police were making enquiries with several people in and around Batcha's house.
“We are trying to know who visited him after March 10 at his house and office. Statements of some persons who Batcha called between March 12 and 16 indicate that he was under extreme pressure. After the CBI questioned him in the 2G spectrum scam, his friends say he expressed fear that he might be arrested or forced to turn approver in the case” the official said.
After perusing the calls made/received by Batcha, investigators found that he had made about 34 calls to one person on March 14 and 15. “He happens to be Batcha's friend since his childhood days. Investigation is on to know details of the conversation between them in those repeated calls,” the official added.
Police are awaiting a final report on the post-mortem examination though doctors concluded that the death was caused due to asphyxia. Some organs taken from the body were sent for chemical examination to rule out poisoning. Also, pathological analysis is on to ascertain whether the injury mark found around the neck occurred before or after death, police sources added.
