Who is stealing actors’ phones from the sets of Bengali show?

There seems to be a sudden obstruction in the shooting of the Bengali television show Gatchara after several actors on the set have started losing their phones. It began with Gourab Chatterjee, who is playing the character of Riddhiman in the show. And then it was Anindya Chatterjee, who found that his phone was missing from his bag. Naturally, the actor duo got angry and reacted accordingly.
Meanwhile, Anindya recorded the entire commission and uploaded a video on social media from the sets. In the video, Anindya was heard saying that the actor firmly believed the 'phone thief' was none other than his onscreen wife Dyuthi, the character played by actress Srima Bhattacharya and he threatened her by saying, "If you don't give my phone back, I will lodge a complaint in Lalbazar."
As the conversation was getting heated, soon everyone realised that Anindya and Srima had planned the entire spoof to have a little fun on the sets.
