The Delhi High Court Monday asked cable operators and internet service providers not to illegally show upcoming Bollywood movie "Dhoom 3".

Justice M.L. Mehta also asked various internet operators to block within 48 hours the sites which illegally show the movie after they received a written complaint from the production house.

The court's order came on a plea filed by Yash Raj Films, the producer of the film, seeking a restraint order against various internet service providers and cable operators on showing the film illegally.

The much-awaited "Dhoom 3", starring Aamir Khan, Abhishek Bachchan and Katrina Kaif, is scheduled for release on Dec 20.
