The two-Dilip Kumar, 31, and Shibu, 30, are RSS workers and were arrested last night, police said.
The incident occurred when some RSS workers barged into the club and allegedly attacked the photographer, Faud Sanea, for having taken a video of their alleged manhandling of a two-wheeler rider during a protest march near here.
A case had been registered against 10 RSS activists under various sections of the IPC including those related to unlawful assembly and rioting besides the Kerala Public Way Restriction of Assemblies and Procession Act.
The case was registered on a complaint by the photojournalist, who suffered injuries on his legs and had been hospitalised.
The protesters blocked the road causing traffic snarls.
The two-wheeler rider, on seeing the march, tried to leave the spot but the RSS workers intercepted him and took possession of the vehicle's key, they said.
On seeing Sanea taking some video shots on his mobile phone at that time, a section of the RSS workers barged into the club and allegedly assaulted him and snatched his phone.
