Story highlights "Peepli (Live)" co-director Mahmood Farooqui faces minimum 7 years in prison

The victim, whose identity is protected by law, was in India conducting research

New Delhi, India (CNN) In what may be a sign of a cultural shift in India, well-known Bollywood filmmaker Mahmood Farooqui has been convicted of raping an American researcher.

A New Delhi trial court found Farooqui, best known as co-director of the 2010 film, "Peepli (Live)," guilty Saturday of raping the 35-year-old woman in the nation's first conviction for an oral sex rape, prosecution lawyer advocate Vrinda Grover told CNN.

India has been taking a closer look at its rape laws after the notorious gang rape and murder of a 23-year old woman on a bus in 2012 as it circled through the streets of New Delhi. A legal amendment was added in 2013 that included forced oral sex as rape in criminal law, Grover said.

The victim in Saturday's conviction, whose identity is protected by law, was in India conducting research and was introduced to Farooqui through a mutual friend, Grover said.
