Noted film maker Rakesh Roshan has sent a legal notice to film financier Prakash Jaju accusing him of making threatening calls to him to settle his accounts with actress Priyanka Chopra who appears in lead role in Roshan's forthcoming film Krrish.

Roshan also asked Jaju to withdraw his defamatory statement in a section of the media that Krrish was funded by illegal money.

Asking Jaju to apologise or face defamation proceedings, Roshan, through his lawyer Dipesh Mehta, said in the notice "your claims about the film's finances are completely unfounded and this appears to be a vain attempt on your part to extort money through unethical means".

"Your threats to stay the release of film Krrish are made with malafide intentions to defame the Roshan family," the film maker alleged in the legal notice copies of which have been forwarded to police commissioner and anti-extortion cell.

Roshan told Jaju that although he may be having dispute with actress Priyanka Chopra over alleged pending accounts, he (Roshan) had nothing to do with his (Jaju's) personal disputes.

The film maker alleged he had been receiving threats from Jaju in the form of text messages, phone calls and letters and described these threats as "a failed attempt of extortion and blackmail".

Roshan also asked Jaju to refrain from issuing such alleged threats and warned to take legal action against him if these were not stopped.
