Most interesting thing about CID is their cast especially ACP Pradyuman, daya, abhijeet and dr salunke and fredie every one has its unique characteristics. The series is story of an organization called cid(crime investigation department).In which thse special officers always become hero at the end of the story, where cid cracks each and every case which it gets, this series has uplifted the image of police in the real society.It is the longest running serial, so far I have seen in indian telivision history, audience love this serial and in the current ongoing episode they done lots of special effects.
