The producer of the movie, Sanjay Kapoor, was taken to the RPF police station at Jamuna bridge for questioning, RPF Inspector Anand Kumar said.
However, after the questioning, the crew was allowed to shoot two lines of a song, he said.
The crew was given permission by district authorities for shooting at various locations in the city including Tajganj Parking, Gulab House, Mehtab Bagh and St John's College. But the shooting was stopped as they entered area under Railways without permission, said Kumar.
