Throughout his career, Roy had quite a few brushes with Bollywood and its alleged nexus with the criminal world. After the family members heard the gunshot, they rushed him to the Bombay Hospital. The funeral will be held on Friday itself.
Police also found his suicide note, which clearly states, "No one is responsible for my death".
He was a well-known figure in the law enforcement world, who handled sensational cases like Indian Premier League betting scandal and the infamous 26/11 Mumbai terror attack. "Such a tragedy", MN Singh, his superior officer at a point was quoted as saying by NDTV.
The officer, regarded by colleagues as committed, sharp and popular, had seven years of service left.
Dr Mary Muckaden, who heads the palliative care unit at Tata Memorial Hospital (TMH), Parel, said, "Depression is common among patients with terminal illnesses".
In 2009, he was promoted to additional commissioner for south Mumbai, a highprofile post that marked the beginning of a phase during which he was entrusted with a range of sensitive cases. "Maybe he felt burdened and decided he could not take it anymore", special prosecutor Ujjwal Nikam said. "It is very, very unfortunate".
Roy was suffering from an advance stage of cancer and had undergone treatment in the United States and Portugal, and the results were encouraging. Soon, he lost his elite posting as the ATS chief and was shunted to an insignificant role incharge of housing. "I used to speak to him every few months". Many people assumed Himanshu was a Bengali because of "Roy" in his name.
"Can't believe the news about Himanshu Roy". In Dey's case, the then chief minister had issued instructions that he wanted an update on the investigations every six hours.
He was instrumental in solving the brutal murder of lawyer Pallavi Puryakayastha - daughter of an IAS couple at the Center - at her Mumbai home in August 2012. Sajjad Mughal was sentenced to life in jail in 2014.
The incident took place in his Malabar Hills residence.
