Terming the Mangalore pub incident as "unfortunate", Karnataka Chief Minister B S Yeddyurappa on Monday said police are investigating the whole episode.
"It's unfortunate. Police are investigating", Yeddyurappa told reporters after the Republic Day function in Bangalore.
He said police have been given a free hand to probe the incident. "No body can take law into their hands", the Chief Minister said.
Fifteen to 20 right-wing "Sri Ram Sene" activists barged into the pub at Mangalore and assaulted boys and girls dancing there.
The activists alleged that the pub owner was allowing the boys and girls to dance in an 'obscene manner'.
Home Minister V S Acharya told PTI in Manipal that stringent action would be initiated against those involved in the assault.
"Thirteen persons have been taken into custody (in connection with the incident). Government will not tolerate persons who take law into their hands," he said.
