Mystery surrounds the death of a 55-year-old cyclist who was found next to his bike in a ditch near Gedney Hill Golf Club.
The body of Allen Nicholas Meade, of West Drove North, Gedney Hill, was found in a ditch with about 18 inches of water on Monday.
A post-mortem carried out on Tuesday proved “inconclusive” and police are waiting for forensic tests to find out how Mr Meade died.
However, police confirmed that although Mr Meade’s death is unexplained, they are not treating it as suspicious.
A Lincolnshire Police spokesman said: “Our efforts to establish details of Mr Meade’s movements on the day his body was discovered have revealed that the last confirmed sighting of him alive was when he left the clubhouse at Gedney Hill Golf Club at around 12.15pm on Monday.
“Mr Meade was discovered in the bottom of a roadside ditch with what was believed to be his bicycle about 200 metres south of the golf club at about 9.30pm on Monday evening.
“It is believed that Mr Meade was travelling south at the time and he was wearing a black T-shirt and shorts, with a camouflaged pattern on the shorts.”
Mr Meade was last seen at his home by a neighbour at 10am on Monday morning before setting out on a silver-coloured mountain bike.
The spokesman said: “Mr Meade was certified as deceased at the scene and it was apparent that he had been deceased for some time.
“The post-mortem carried out on Tuesday was inconclusive and we now await the results of forensic tests to establish how he died.”
An inquest is expected to be opened by the Coroner for south Lincolnshire, Professor Robert Forrest, later today when it will be adjourned to a later date so that police enquires can continue.
Anyone with information about Mr Meade’s movements on Monday should call 101, stating incident 489 of June 9.
