A third man has been arrested following the death of Briton on a film shoot at an Indian train station.
Gustad was shooting at a railway station for a new film
Hadley D'mello has been held along with Bombay Central's director Kaizad Gustad and his assistant Ashish Udeshi after Nadia Khan was hit by a train.
Miss Khan, 26, from Newbury Park, north-east London, died during the shoot in Bombay (Mumbai) on May 25.
Mr Gustad has been charged with manslaughter, negligence during shooting and fabricating evidence.
Transport police in Mumbai said the crew did not have permission to film at the Mahalaxmi railway station.
Miss Khan's elder sister, Ruby Rizvi, said her parents were "shattered" by the death.
She added: "Nadia was a friend of Mr Gustad. He did offer her a position last year, she was assistant director.
"She was looking for experience - that is partly the reason she went out to India. It is her first time over there."
It is believed that it was her first day on set and that she had been talking on her a walkie-talkie cueing the actors and holding a script when she was struck by the locomotive.
Police in Bombay claim the film crew initially told officers and hospital staff that Ms Khan had died in a road accident.
But Mr Gustad said last week that he welcomed the investigation and said he and his crew voluntarily went to the police.
Mr Gustad and Mr Udeshi appeared before a Bombay court last week and were remanded in police custody until 10 June.
If found guilty of manslaughter, Mr Gustad could be jailed for up to 10 years.
