Tens of thousands of pounds worth of antiques have been stolen from homes.

The thieves have raided the homes in West Sussex while the occupants are asleep, always making off with valuable items – on one occasion stealing a seven-foot grandfather clock.

Among the items taken during the first burglary between 9pm on January 2 and 9am on January 3 were more than a dozen ivory figures, porcelain and jade perfume bottles and boxes from the Far East, a series of paintings and a dozen Royal Doulton figurines of ladies.

On this occasion the raider targeted the property in Amberley Drive, Worthing, while the elderly resident was asleep.

The second burglary took place in in Old Fort Road, Shoreham, between 3pm on January 2 and 5am on January 4 while the owner was away.

A large amount of valuable gold jewellery was taken along with oil paintings, bone handled cutlery, watches, Hornby 00 gauge railway items, 60 collectable American tobacco silks and a pair of foot high blue Chinese dragons from the Far East.

The third burglary was at a home in Washington, near Steyning, between 1.50am and 2.50am on January 7 while the residents were asleep.

Among the items taken were a number of brass clocks, silver candlesticks and cutlery, Chinese vases, a satinwood table and a walnut cupboard.

The fourth burglary was at a home in East Street, West Chiltington, near Horsham, between 11.45pm on Thursday and 9am on Friday.

The items taken include a seven-foot grandfather clock, a number of paintings, two TVs and a DVD player.

Detective Constable Jon Stadius  said: "In each case the burglars appear to have selected carefully the items they think are of the most value and left other items behind.

"Large numbers of items have been taken so a vehicle would have been needed to transport them away. Some of the items, such as the grandfather clock, were extremely heavy so it is likely a number of people have been involved.

"We would like to speak to anyone who has seen any people or vehicles in the areas of the burglaries recently who looked suspicious or out of place.

"We are also keen to speak to anyone who may have seen the items for sale or has been offered the chance to buy them.

"Please contact us if you know anything at all so we can catch those responsible."
