A source says, "The unit ran into trouble while shooting on the streets. Most houses have a smoke detectors there as the authorities are strict about such things. They were filming a fire scene and the smoke alarm went off. And when it did, someone alerted the fire authorities, who came immediately to check if a fire had broken out.
When they found out that the false alarm was caused by the shooting, they were very irritated. They wanted the unit to pay a hefty fine. Punit and the production team negotiated with them for a couple of hours over it. Shooting got stalled for a few hours."
On Saturday at 5 am, Imran had tweeted, "Our smoke machine has set off the fire alarm. Which has set off every alarm on the block. Fire brigade are enquiring what exactly we're upto. Entire unit has spilled out into the street. Negotiating terms with fire department. Seems there's a 15,000 dollar fine for false alarms.
Alarm switched off, fire department appeased, and we're back to work!" When someone asked him whether they had to pay the huge fine Imran tweeted back, "negotiations are still underway. The burglar alarm in a Sunglass Hut next door went off as well, so it's a "security breach"."
Producer Karan Johar says, "I can't comment on it."
