The actor was shooting one of the crucial scenes from the film at Kamalistan. He had a scene where he enters a house on fire. Shahid has been shooting this scene for last 3 days and it was a very important sequence for the film.
Despite of having a great action team and necessary precautions taken on the sets, as soon as Shahid Kapoor gave his shot and was getting out of the house, some hot solution fell on his back.
A source said, 'The fire is created artificially by a chemical solution. However the solution was excess and hence dripping. The solution was hot and it immediately bore holes in Shahid's t-shirt... The solution fell on his back and fore arms. Shahid half sprinted while removing his t-shirt.'
