Last night around 2am, a couple start ringing our door bell and banging our door, stating they have lost their iPhone and their iPhone location shows it is at our place. We dint open the door but they kept insisting, then swearing and then abusing stating that the IPhone is in our house. We call up the police and explain them what is happening, also inform the couple that we have got the police involved and gave them the reference number. The iPhone couple then leave and are back again after 10 mins and start abusing, banging the door and ringing the bell. They threaten that they will break the door and knick us if we don't give the phone. They say they are damn sure the phone is with us since this is a shared accommodation ( which it is not, we are a family with 2 young kids). The Iphonr couple then realise we have cameras on in the house and then disappear again to be back again in 10 mins. This time the women says, she means no harm and she lives down the street and wants her iPhone back. We politely ask her to leave since she is trespassing and get the police involved if she suspects we have the phone. They roamed around the street waiting for someone before they disappeared and haven't been back since morning. My children are obviously very petrified. Needed to understand if this is a scam. We obviously have nobody's iPhone. The women was extremely violent.
