More than 1, 000 Shiv Sena activists have been arrested for vandalising cinema halls and multiplexes that will screen Shah Rukh Khan starrer "My Name Is Khan", officials here said Wednesday.

Till Wednesday morning, 1, 023 Sena workers had been arrested under various charges like rioting, damaging property, unlawful assembly and trespass. They had also attacked Broadway cinema at Kandivalli East in the city.

Meanwhile cinema halls in India's film capital Wednesday stopped advance bookings for Shah Rukh Khan starrer "My Name Is Khan" following violent protests by Shiv Sena activists.

Multiplex chains like PVR and Cinemax withdrew their advance bookings for the film, as did single screen theatres like Mehul in Mulund and Shreyas in Ghatkopar, their officials said.

"We have shut the advance bookings for the film as of now. It may open around 4 p.m. today but nothing is certain at present," Girish Wankhede, deputy general manager (Corporate Communication) of Cinemax, told.

Pramod Madhve, an official from Mehul Theatre, said: "Nothing about the film's release is fixed yet. We hope to receive updates by tomorrow. But the advance bookings have been shut for now."

A Shreyas Theatre official said: "Bookings have been closed as of now, we should be in a position to tell you about the release by tomorrow."

According to TV channels, major multiplexes like PVR, Big Cinemas, Adlabs and Fun Cinemas too have closed their advance booking windows for "My Name Is Khan".

Activists of the right wing Shiv Sena have been demonstrating against the movie since Shah Rukh supported the inclusion of Pakistani cricketers in the Indian Premier League (IPL).

The activists have been vandalising cinema halls and tearing up hoardings, despite the Mumbai Police assuring security cover at the 63 cinemas and multiplexes that are still scheduled to show the movie here from Friday.

"We don't see it as a threat to the release of the movie but it's a threat to the law and order situation," Himanshu Roy, joint police commissioner (Law & Order), said Wednesday.

"My Name Is Khan", set in post 9/11 US, is releasing worldwide Friday.
