Five burglaries in the Chichester area - some of which took place while the homeowners were asleep upstairs - are being investigated by police.
West Sussex CID are looking into the burglaries from the Summersdale area overnight on Friday, February 17.
Various items of property were stolen during the break-ins, including electrical and computer equipment. Some of the stolen property was discovered discarded outside the houses that had been burgled.
Police have released a photo of a 19th century ornate mantle clock which was taken in one of the break-ins in the hope that it can be traced and reunited with its owners. It is 26cm in height and stamped ‘Ramilo Paris’.
DC Jon Woolley, from the Priority Crime Team, said: “Fortunately this type of crime is quite a rarity in this part of Chichester but it is obviously deeply distressing for the victims.
“We are undertaking numerous enquiries to try to trace the property that was stolen and also to find those responsible to bring them to justice.
“This is also a timely reminder for homeowners who have alarms to always ensure they are set in all areas of the house when the property is occupied overnight.”
It is believed that the break-ins are linked to an on-going series of house burglaries across the southern part of West Sussex known as Operation Etna.
Detectives are working closely with colleagues in Hampshire as its believed the crimes could also be linked to others that have been committed across the border.
If anyone has any information about the burglaries or the property stolen then contact Sussex Police on 101, quoting serial 609 of 18 February.
