A number of pro-Tamil outfits had staged agitations here yesterday against the conduct of Indian Premier League, saying it was being held to divert attention from the ongoing protests seeking formation of Cauvery Management Board.
Police said the 11 were also arrested for raising slogans on the Cauvery issue.
Their action had amounted to affecting public peace, a police release said.
They were produced before a court and remanded to custody, it added.
When the accused were stopped from proceeding to the stadium, they allegedly attacked a policeman, it said.
Police were on the lookout for two other persons wanted in connection with the incident.
