Jyotirmoy Dey was the third journalist in India to be killed in the past six months, a media watchdog said Tuesday.
There have also been 14 attacks on the Indian media in the same period. In all the cases, investigations are under way but no arrest has been made, said Geeta Seshu of the Free Speech Hub (FSH) of The Hoot.
Dey, a Mid-Day reporter who used to write on the Mumbai underworld, was shot dead June 11 by four motorcycle borne men.
Sushil Pathak, a journalist with Dainik Bhaskar in Bilaspur, Chhattisgarh, was shot dead on December 20 while returning home.

On January 23, reporter Umesh Rajput of Nai Duniya was shot dead by two masked assailants on a motorcycle. A threatening note was found near the scene of the crime.
It said: "Khabar chaapna band nahi karoge toh mare jaoge" (If you don't stop publishing news, you will be killed)."
The Free Speech Tracker, set up last year by FSH to monitor instances of violations of the freedom of speech and expression, says attacks on journalists and intimidation of editors and writers continue unabated.
Seshu observed: "The impunity with which these attacks have taken place only shows that, in India, freedom of speech and expression cannot be taken for granted."
FSH has listed 14 instances of attacks on journalists.
