An FIR was registered against the producer of the Hindi film So Long Valley for allegedly cheating model Ruchi Gujjar of Rs 23 lakh, a Mumbai Police official said on Saturday.

Viral videos, meanwhile, showed Ruchi purportedly slapping the producer, Karan Singh, during the movie premiere event held on Friday night.

An Oshiwara police station official confirmed that an FIR was registered against Karan under various sections for cheating on a complaint lodged by Gujjar on Thursday.

The model alleged that Karan had taken money from her under the pretext of launching a movie project for a television channel, and promised her a share in the profit and on-screen credit, the official said.

“The complainant stated that the project never materialised and Karan didn’t return her money,” he said.

Ruchi’s lawyer said a separate FIR would be lodged against Karan at Amboli police station for assaulting the actor.

So Long Valley is a Hindi-language crime thriller film starring Tridha Choudhury and Vikram Kochhar.
