An India Police Service officer of the 1988 batch, shot himself with his service revolver at his residence.
In his sprawling career, Roy headed the Maharashtra Anti-Terrorism Squad (ATS) and also worked as the Joint Commissioner of Police (Crime) from 2012-2014 in Mumbai. He had been credited with cracking several high profile cases in the city. Roy had set up Mumbai’s first Cyber Crime Cell.
Roy is also credited with leading the investigation into the IPL betting scandal.
Former Mumbai police commissioner M N Singh termed him a courageous and hardworking officer.
"He was suffering from cancer but he was fighting it. It is very unfortunate that he had to end his life like this," Singh was quoted by PTI as saying.
He was then transferred to the state ATS. During his tenure as the agency's chief, software engineer Anees Ansari was arrested for allegedly planning to blow up the American school at the Bandra Kurla complex.
