Late Tuesday, Rishi took to the social networking site to rebut allegations made by a Congress leader, accusing him of being present at an illegally organised bullfight in his father's legislative constituency of Mandrem.
Rishi, 21, whose social media profile claims he is a singer, musician, student and a real-estate businessman, claims that the charge levelled by Congress organising secretary Durgadas Kamat was baseless.
Rishi issued him a "last warning", and signed off the Facebook post as "CM's Son".
Rishi's clarification post says: "Dear Durgadas Kamat, Please reveal the rest of the photos too... let me see myself at a venue when actually I do not exist there. I seriously wont tolerate this kind of shit. Please take a note of it..!! boss DK (i mean to say Boss durgadas kamat) (adds a smiley), get correct information first and then post on fb! Regards, 'CM's Son'."
Earlier during the day, Kamat, uploading two photos of buffalo and bull fights with people ringed around the animals in both instances, alleged that the fights (dhirio) were held in Mandrem.
"Dhirio in presence of CM's Son," Kamat said while appealing to animal lovers to condemn the fight. Rishi, however, does not feature in the images uploaded by Kamat in his Facebook post.
Later, while hash-tagging another friend into the comments section, Rishi says: "This gona b last warning for him.. if again he does then i won't waste time showing him real me (adds smiley)."
Once a popular tradition, bull fights or dhirio were subsequently banned by the Bombay High Court bench in Goa on grounds of cruelty to the specially reared fighter bulls.
But that has not stopped the bull fight aficionados from organising fights illegally using Facebook, Whatsapp and SMSes to alert eager audience about a scheduled bull fight mainly in coastal Goan villages, like Agacaim, Mandrem, and Benaulim.
Incidentally, the person who first alerted the media about a bull fight being organised in Parsekar's constituency was Bharatiya Janata Party (BJP) legislator Vishnu Wagh.
