A murder investigation has been launched after what are believed to be remains of a body being discovered in Ellesmere Port.
Officers were called to a house on Hylton Court on Tuesday after a tip off from the public in connection with a 35-year-old man who had been missing since 2009.
Police began searching in an outbuilding of the house and found remains which are still to be confirmed as human.
Formal identification has not yet taken place but the victim is believed to be Christophe Borgye, a French national who was reported missing in May 2009.
His family in France have been contacted and made aware of the investigation and discovery.
Two men have been arrested on suspicion of murder. One of them a 35 year old man detained earlier in the week has been sectioned under the Mental Health Act.
Detective Chief Inspector Simon Price from the Major Incident Team said:
"Incidents like this are thankfully rare, especially in Cheshire and I appreciate that the public may be concerned about the police activity in the area. I want to reassure them that this is a contained incident, we have arrested two men and have a team of officers working on the case.
"Formal identification is going to take some time but based on the information we have at this time we believe the victim is Christophe who was known to the man in custody.
"If anyone has any information that may assist us in our investigation I would urge them to contact us."
