Indian Railways — Security in train

While i was travelling in train from delhi to ambala in train no-12217 which is kerala samparkkranti express, there was no police officer in train and mobile stealing happened with one of the co-passenger near azadpur mandi. There was senior citizen with which it happened and he was in complete shock.
When asked from the tt about reporting fir, he told to report in chandigarh police station which was their destined place but chandigarh police told them to file case in area where it happened which meant to be azadpur near delhi, a complete harassement for senior cititzen, please provide police with fir in train or atleast police.
