MK Ganapthy was found hanging from the ceiling fan in a room at a lodge in Madikeri.
Various organisations today staged protests in the city demanding arrest of persons named in the TV channel interview of Deputy Superintendent of Police Ganapathy who allegedly committed suicide on July 7.
BJP leader Ravi Shankar Mijar, speaking at the protest organised by the party before the Deputy Commissioner's office, demanded arrest of the alleged abettors in the case.
He said Mr Ganapathy was an honest police officer and alleged that harassment by a former Home Minister and two senior police officers had led to his suicide.
Speaking to protestors in front of the DC office, Dakshina Kannada district president of the 'Karnataka Rakshana Vedike' Anil Das said persons named in the police officer's pre-death declaration should be arrested.
The Rakshana Vedike wanted the government to provide Rs 10 crore compensation to Mr Ganapathy's family.
Dakshina Kannada district JDS president, Mohammed Kunhi told reporters at a press meet here that the suicide was an example of the "anti-people" policies of the Congress government.
The Karnataka government has handed over to CID the investigation into alleged suicide of the Mangaluru Deputy Superintendent of Police which has triggered a storm with the police official in his pre-death declaration accusing a senior minister and two top officials of harassing him.
