Royal Mail has said it has no choice but to deliver post to a caravan sited illegally on land behind Panmurefield Village outside Dundee.
The caravan was moved on to the site on North Balmossie Street, between Panmurefield Village and Wyvis Road, in September.
Since then the owners of the caravan have erected steel fencing around the caravan so nobody can see in.

They have now also installed CCTV cameras in the trees above the caravan and even a mailbox.
Planning permission was sought to build a house on the site in January but refused by Dundee City Council.
A Royal Mail spokeswoman said: “If we get mail for an address then we have to deliver it.”
A woman in the compound refused to speak to The Courier when approached last week.
