Residents in the Augusta Park area are being asked to remain vigilant following a suspicious incident on the afternoon of Tuesday 2nd May 2017.
It is alleged that a male and female duo attempted to gain access to a house in the Chariots area of the development.
An eye witness said, "A young couple were looking in people's homes and garages. I saw the girl looking at a neighbours house whilst the man went towards the open garage door. I believe both were confronted by the owner and they than ran off.
"They were both in their early 20's, the bloke had a grey top on. I noticed the girl/lady just looking at the house at first then saw owner appear and go to the garage. Then this bloke appeared. Clearly words were being said and they run off."
If anyone sees anything suspicious, call Hampshire Police on 101.
