Mutalik, who was in the state capital attending a programme at Town Hall on Thursday, Feb 11, got a taste of his own medicine when a group of people caught hold of him and smeared black colour on his face.
Sene supporters rushed to the rescue of a evidently jolted Mutalik, who has been going around Bangalore over the past few days speaking against the Valentine's Day.
When he was attacked, Mutalik was taking part in a discussion organised by a Kannada TV channel on Sene's opposition to V-Day celebrations.
The police has detained six people in connection with the incident.
Sene has issued a threat to marry off people celebrating Valentine's Day. This is similar to the threat issued in 2009.
Before launching their first war against Valentine's Day in Feb 2009, Sene had hit the headlines for attacking women in a Mangalore pub in Jan 2009.
Even though this is the first time people protesting Sene's threats launched a physical assault, in 2009 Muthalik was left red-faced after activists supporting people's right to celebrate V-day sent truck-loads of Pink Chaddis.
This was also the revenge of the urban woman against the Mangalore pub attack.
