Just recieved a email about child offences?

This is a scam , i received one also and i was not even using my pc at the time and i also have never done anything to break any laws. Although i did add a few people from a chat room to talk about general stuff. I have compared the email you received with the one i got and it has the same reference number, person host number. so its defiantly a scam and you have nothing to worry about :) Also the part with your ip number is something they do just to scare you, that information can easily be gotten by anyone just by pinging or using a trace route on your computer. They may have got the ip to ping from msn. So again there is nothing to worry about, i would just delete the email and forget it happened.
