Often referred to as "Arnold Schwarzenegger" of Mumbai Police, Roy is survived by his mother and wife.
In a separate interview that Nagarkar gave to The Hindu, the doctor said it wasn't so much the disease itself but the emotional trauma it had on him that may have led to Roy taking the extreme step.
Condolence messages flooded Twitter after the sad piece of news about Himanshu Roy's suicide left the Mumbaikars in shock. The case is being investigated by the Crime Branch.
A fitness freak, he was tall, well-built and handsome and often known as "Body Builder" and compared with Arnold Schwarzenegger. He was leading the investigation into the IPL betting scandal. Soon after the incident, he was rushed to Bombay hospital.
In 2012, he was among the officers handpicked by then Home Minister R.R. Patil to oversee the transfer of Pakistani terrorist Ajmal Kasab, who was found guilty in the Mumbai terror attack, from Mumbai to Pune.
According to Dr. Nagarkar, Roy first developed cancer in his kidneys in 2000, "He underwent extensive chemotherapy and surgery and succeeded in removing those tumours from his kidneys". The 1998-batch IPS officer leaves behind a legacy of pioneering police work, including his efforts against cyber-terrorism, match-fixing and crimes against women.
"He had been suffering from cancer for almost two years and it seems he died due to the frustration", former Mumbai Police commissioner M.N. Singh told ThePrint. "This was revealed in the suicide note written by him", a press staement released by Mumbai Police said.
Before being promoted as ADG (Establishment), Roy had been posted as Superintendent of Police (SP), Nashik Rural, SP Ahmednagar, DCP Economic Offences Wing (EOW), DCP Traffic, DCP Zone I, Mumbai, Commissioner of Police, Nashik. "It's a great loss to Mumbai police".
Roy had a splendid career in which he cracked several high-profile cases and handled important responsibilities.
