Kolkata: A retired IPS officer was found dead under mysterious circumstances at his flat in Salt Lake area, Kolkata, police said.

Gaurab Chandra Dutta’s body was found on Tuesday evening. Police said it was found in a pool of blood and a note was recovered nearby.

Dutta, who had solved several important cases during his tenure, had retired last year. He lived alone in his house, police said.

“We have started an investigation in the case,” an official of the Bidhannagar Police Ccommissionerate said.

Meanwhile, the Supreme Court on Wednesday will hear a plea filed to demand a CBI probe into the murder of three BJP workers in West Bengal.

The apex court is hearing a petition filed by BJP leader and lawyer Gaurav Bhatia, who sought a Central Bureau of Investigation (CBI) probe into the matter.

During Tuesday’s hearing, Bhatia had argued for a CBI investigation of the murders. “The brutal murder of three WB BJP workers is a fit case for a CBI probe and if this case is not fit for a detailed investigation by CBI, then no case comes under the ambit of CBI probe,” he argued.

On May 30, 2018, 18-year-old BJP worker named Tirlochan Mahato was found hanging from a tree in Purulia’s Balarampur district. After this incident, another BJP worker, Dulal Kumar was found dead in a similar manner in the same district.

On July 28, BJP leader Shaktipada Sardar was hacked in West Bengal’s Diamond Harbour area. These deaths had sparked an outrage in the state with the BJP blaming the ruling Trinamool Congress for the attack.
