The Maharashtra government has transferred the probe into the Charudutta Deshpande alleged suicide case to the Central Bureau of Investigation.
State Home Minister R. R Patil took the decision on Thursday after repeated requests from the deceased's family and as well as the Mumbai Press Club.
A former journalist and corporate affairs and communication chief at Tata Steel, Deshpande was found hanging in his Vasai home on June 28, 2013.
The case was being pursued by the Thane police.
However, Mr. Deshpande's son Gaurav and brother-in-law Mahesh Bhatkal recently wrote to Mr. Patil alleging shoddy police investigation and sought a probe by an independent agency.
Deshpande's family had said that the investigation into charges of abetment against Tata Steel officers had run aground and were deliberately not being pursued by the Thane Rural Police.
The FIR lodged at Vasai Police station had charged Prabhat Sharma, deputy corporate communications manager at Tata Steel as the prime accused in abetment of suicide.
In its letters to the Home Ministry, the Mumbai Press Club had also presented the provisional findings of the psychological autopsy conducted by psychiatrist Harish Shetty.
The findings claimed that Deshpande did not suffer from clinical or other forms of depression but it was months of harassment and mental torture had led him to take his own life.
“Charudatta Deshpande did not suffer from depression or any serious mental illness before his demise. He appeared to be troubled by stressors from his last employment and felt threatened weeks and months before his death," the report said.
