How to interrupt Dawood when he interrogates the mole?

I tried switching on the fire alarm, dropping stuffs near him, shooting him, shooting the mole, dressing as the artist and showing up to a guard to let him call Dawood, and none of them worked.

Well, I just made it. It seems like that I’ll have to wait until the interrogation starts - when the conversation starts. Then whatever you do to interrupt it would work, such as starting a gunfire.
