Found this link online and I think it should be some what useful. To register a complaint now one doesn't need to visit a Police Station and instead can register a complaint online through below link. https://india.gov.in/services/register
We find a search box from the above web page where we can enter any Indian state name and find respective useful websites from those states. For example I picked below link from the resulted list as searched for 'Tamil Nadu'. http://www.tnpolice.gov.in/CCTNSNICSDC/Index?1
I somehow feel that any complaints registered through online will be taken up/traced more effectively than the ones registered through personal visits. I also see few links for mobile apps, but not sure if the Mobile Apps are effective enough as I'm yet to try. Will give a try and update my experience later.
If we come back to the above discussed scenarios, then we may not get instant help from these websites but surely we can trace the rogues and lessen such activities.
