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.
