Top Indian film producers and movie stars are increasingly being targeted for extortion by underworld gangs, although police have been frustrated over the refusal of the film personalities to lodge formal complaints, the Times of India reported today (Monday). "Many actors and actresses submit to the demands of the extortionists," one unnamed police officer told the newspaper. "In some cases, they have given money to gangsters even after being provided with police protection." Another source said that the gangs are in some cases demanding overseas distribution rights. "If producers are reluctant to part with overseas rights, they have to face the gun," the sources said.
