CID Episode regarding ACP Pradyuman.

So there was an arc of 4-5 episodes I guess in which there was a murder in a bunglow. And DCP Chitrole made Daya and Abhijeet to lead the case and during the investigation they find out that ACP Pradyuman had stolen evidence from crime scene which was present near a flower pot. I am unable to find that arc's ending please tell the episode number.
