Nationalist Congress Party (NCP) activists Monday protested outside two cinema halls here exhibiting the latest Aamir Khan production Delhi Belly due to its "vulgar and objectionable" content, police said.
The managements were forced to cancel the afternoon shows.
Over 50 angry NCP activists, led by local corporators Anil Pharat and Prakash Gaondi, created ruccus at the Padma and Parvati cinema halls where the afternoon shows had started.
They shouted slogans, tore off the movie posters and banners and attempted to barge into the theatre premises, demanding cancellation of the show.
Their ire was also directed at the censor board, which they said had cleared objectionable dialogues, explicit erotic scenes and the song DK Bose.
The protesters demanded deletion of the song, offensive dialogues and explicit scenes on grounds that they corrupted the mind of the youth, especially college students, who have been queuing up to watch the movie.
Police said that around 20 NCP activists were detained and additional security has been provided at the two cinema halls.
An officer from Kolhapur's Laxmipuri police station said that the NCP had told the two theatre managements and the police Sunday that the party members will demonstrate if the shows were not cancelled.
