Former Team India captain and Cricket Association of Bengal (CAB) president Sourav Ganguly had received a death threat letter, following which he filed a complaint on Wednesday, police said.
A senior police officer of the Kolkata Police told PTI that Ganguly lodged his complaint at Thakurpukur Police Station.
"We are looking into the matter. We are checking whether it's a genuine or fake letter. Our officers are examining the letter," he said.
Ganguly had received the death threat letter via post addressed to his Behala residence on January 7 asking him not to attend a facilitation programme in West Midnapore district.
