Kolkata: Legendary Filmmaker Yash Chopra on Wednesday requested the central government to take steps to end the menace of piracy.

'Whenever a film releases, the first to get benefit out of it are film pirates. Our existence is at stake due to this. The center needs should do something,' Chopra said.

Chopra regretted that most of the government officials don't know how to use the law for dealing with the people involved in piracy.

'It is very heartening to say but it is a truth that most of the police people don't know whom to put behind bars and whom not to,' Chopra said.

Chopra also lauded West Bengal Chief Minister Mamata Banerjee as one of the most dedicated politicians she has ever come across.
