Police are appealing for information after a large quantity of cash and diamond jewellery worth thousands of pounds went missing from a home in Friston.
There was no sign of a break-in at the property in Warren Lane but the residents noticed a number of items had gone missing a few months ago.
Several hundreds of pounds in cash and two rings were taken .
The items were stolen some time after the middle of October.
The first ring is gold with a large pear-shaped single diamond worth around £4,000.
The second ring is a gold wedding ring, also set with a diamond and worth more than £3,000.

They are asking anyone who has seen the items or been offered the chance to buy the expensive jewellery to get in touch and help with the investigation.

“I would like to speak to anyone who may have seen anyone acting suspiciously in Warren Lane over the last few months and who could describe them to us.
“I would particularly like to speak to anyone who may have been offered the chance to buy the rings.
“If you have seen them or know where they could be, please contact us.”
