A fifth man arrested on suspicion of murdering businessman Julian Gardner at his East Sussex farm has been bailed.
Sussex Police arrested and questioned a 56-year-old man from Ashford in Kent after he handed himself in at Eastbourne police station on Monday.
Mr Gardner, 53, died on 11 October from multiple injuries after apparently disturbing thieves in outbuildings at his Robertsbridge farm.
Four other men from the Ashford area have also been arrested and bailed.
The man who was released on Tuesday morning was bailed until January 2011, officers said.
Police said two addresses in Kent were searched on Friday.
Officers believe Mr Gardner was the victim of a botched robbery at Bush Barn Farm where he ran an agricultural and car repair business.
One theory is that he was crushed between two vehicles.
Mr Gardner's body was found by his business partner. He had suffered several fractures and compression injuries.
Two burnt-out vehicles were found abandoned a few miles away.
