Items thought to have been stolen are being posted on a website in a bid to reunite them with their owners.
Detectives from the Priority Crime Team seized the items, after a man was arrested in London by the Metropolitan Police, which included large amounts of jewellery and watches.
Letters have been sent to victims of burglaries in Mid Sussex but pictures of items which have not been claimed are now to be published on a website in an attempt to returned to their rightful owners.
Detective Constable Pippa Hannard said: “We believe most of these items have been stolen and desperately want to make sure their owners receive them back again. Not all the items are of particularly high monetary value but I’m sure a lot of it will have sentimental value to the owners concerned.
“We’re asking for anyone who has reported burglaries in Mid Sussex since October 2012 to have a look at the website and see if they recognised anything. If so please fill in the form and we will take it from there.
“You can find all the pictures on our website at http://property.sussex-police.co.uk/regatta”
A 34-year-old man has been arrested on suspicion of burglary and been bailed until April 3.
