Hi, Sex chat is illegal in india as per IT act. You may be convicted under the same after the set of legal process. It is the act by set of people over WWW ( they could be from cyber crime department, hackers .. etc.,). In your case, they are able to trace you using the IP address(they must be already having your personal details hacked from your PC using trojans,antiviruses,malware .... etc), So, it does mean they could be detectives but unless i discuss with you i would not able to understand their intention.
