Mumbai: A senior BJP party worker from Vasai created a ruckus and assaulted the theatre manager when the screening of a Marathi film stopped due to a technical error on Friday evening.A Non-Cognisable (NC) offence has been registered with the Manickpur police. The senior party worker Ramdas Meher went to watch the Marathi film 'Natsamrat' at K T Vision Theatre, Vasai (west) at 5.45 pm. He was accompanied by his family and a few party workers. The film screening was delayed by about half-an-hour leading to unrest among the audiences. The audiences, however, stayed put in the theatre.By 6.15 pm, the movie finally began but within half-an-hour, it stopped due to a technical problem. Meher along with party workers barged into the cabin of the manager Christoper Nicholas and assaulted him. He slapped the manager and dragged him outside the theatre where he was made to apologise to the public.While Nicholas apologised to the audience and assured refund of ticket money, Meher allegedly demanded twice the ticket cost. The entire action was captured in the Closed Circuit Television (CCTV) of the theatre. Nicholas approached the Manickpur police who took an NC.Meher alleged that the technical error was deliberate as it was a Marathi film and it was an attempt to take off the movie from the screen. Nicholas said that a sudden problem of sound was experienced during screening and technicians were fixing it when the gang of BJP activists arrived and assaulted him.The film starring actor Nana Patekar released on January 1. Audiences said that K T Vision has just one show of the film (5.45 pm) and it has been running house full.
