iphone thefts
I had my iPhone 6+ stolen from me in Barcelona metro two weeks ago. It will be deleted as soon as it is going to be connected to the internet. But in the past two days I have been receiving strange messages from my iMessage from address: "apple.icloud.server.imessage.notice.kabc@icloud-admin.com" and the message says: " (Find my iPhone) Your Apple ID was signed in iCloud on Berkley Lyon's iPhone.Mac os:ios 9.3.2. If you believe an unauthorized person accessed your account, please sign in and manage you account by going to http://Apple.find.ios-es.com/us (Apple support)"
I have checked my iCloud for "Find my iPhone" and the lost phone is still pending to get connected to internet. Does anyone know what these messages are? Are these being sent to me by Apple or the thieves?
Thanks
iPhone 4, Windows 7
