Detective Sergeant Dave Grover said: “We are urging people to stay vigilant and keep an eye on neighbours’ properties during the daytime, as most of these offences have happened between 8am and 5pm. You know what is suspicious behaviour in the area you live and if you do see anything please report it to us.
“In some of these offences, items found in the garden, like a spade and a garden chair, were used to gain access to the property. Please make sure there is nothing left outside your house which could be used to break into your property.
“We are releasing an Efit of a man who was disturbed at the break in at Orchard Dell. Do you recognise this man? As we are linking all these burglaries, have you seen this man in the area of any of the other break ins.
“Some of these items are distinctive such as the watches. Have you seen any of these items for sale or been offered them to buy?
“Anyone with information or has seen anything suspicious is asked to contact police on 101 or email firstname.lastname@example.org quoting Operation Bourne.”
