Thieves climbed onto a conservatory roof during the day to force their way through a window - just one day after a man was seen taking photos of the house.
It happened on Monday between 8.30am and 3.15pm in Tewkesbury Lane, Monkston, when offenders got in through a rear first floor window.
After an untidy search of the home they stole a safe containing gold jewellery, which was later found empty near Campbell Park.
On Sunday, the day before the burglary, a man was seen photographing the property before getting into a small silver car, which has been described as possibly being a Skoda Fabia.
