An elderly lady left her bathroom to be confronted by a man standing in her house with a red rope.
It happened on Monday, November 26, at one of the farms on Farm Road, Edgeworth, between Stroud and Cirencester, at 2pm.
The woman left her bathroom to find a tall male wearing dark clothing.
He was holding a length of red rope and was standing at her front door, already inside the house.
He said 'sorry' and he left, and was said to have looked surprised at suddenly seeing her.
Nothing was taken from the house and no one was hurt.
A police spokesman said: "At this time there is no definite explanation as to what he was doing or who he was, but please be vigilant and if you see this male or something similar happens, please report it by ringing 101 or emailing our control room at forcecontrolroom@gloucestershire.pnn.police.uk."
