The cast and crew were in Ramoji Rao Film city in Hyderabad to wrap up the shoot and the duo turned pranksters there.
They planned the entire prank in advance and took a spot boy under their confidence. The prankster duo made the spot boy wear white clothes and told the crew members that the set was haunted and that there was a ghost on the sets, as it was a night shoot and quite deserted.
A source close to the media said, "Ajay sir and Rohit sir have been constant pranksters on sets. Once, they baffled and scared all of us by dressing up a spot boy in white clothes and making him behave like a ghost."
"Also, they always tried to scare us by telling stories of the ghosts in our hotel room," the source added.
Singham Returns co-produced by Ajay Devgn Films, Rohit Shetty Productions and Reliance Entertainment also stars Kareena Kapoor which will release on August 15.
