friedie senior to sachin

sachin joined much latter than then why does sachin not call him 'Fredie sir"as vivek does. i know the fact that sachin used o play a role in CID SB cases but there his name was different.so assuming that he was a different person.

no need to talk about sachin.
there is no sachin for me in cid team.

I HATE SACHIN 😡  
YA RIGT USE FREDDY SIR KO (SIR)  BOLNA  CHAHEYE

Stop cursing people.

Its because of FW introduce Sachin as senior to Fredie. So Fredie calls him Sir.

when SACHIN was caught in his first episode, he said that he was an inspector somewhere else and they sent him in cid..so that's why sachin is senior to freddy-vivek-tasha-kaajal
