A day later, the bodies of the two 84-year-old men were found after officers were called to a property in Cowick Lane at 1pm on Tuesday.The second house is a mile and a half away from the first, and some houses on Cowick Lane sell for more than £1million. Forensic police officers were seen on Wednesday at a large, detached house on the road, where one neighbour said the two men found dead were twins.Police arrested the 27-year-old man on Tuesday and he remains in police custody.Detective Chief Inspector Roy Linden, from the major crime investigation team, said: “At this time there are several and significant common factors between the two addresses.”In terms of the level of violence used we decided last night to link the investigations. Originally they were treated as two separate murder investigations. One suspect has been identified and formally arrested yesterday evening.””There were significant levels of injuries and some commonality between the two incidents, which led us to link those investigations and treat them as one single investigation at the moment,” he said.Superintendent Matt Lawler told reporters the force had “yet to establish a clear connection between the parties involved”.

Forensic officers at Bonhay RoadCredit:Dale Cherry “I know that everyone’s immediate thoughts will be with the family and friends of these gentlemen, and as you would expect, we are providing as much support as we can to them.”The investigation is being led by our major crime investigation team, supported by local detectives, forensic staff, family liaison officers, and an extensive range of other specialists who have been working around the clock since Monday afternoon.”Residents in the area of both Bonhay Road and Cowick Lane will continue to see police cordons today as we continue vital work. The local neighbourhood team will be out on foot over the next few days in order to provide advice, support, and to answer questions.”While a man has been arrested on suspicion of murder in relation to these incidents, we must keep an open mind and avoid speculation as we are still in the very early stages of what is already a complex investigation.”We have therefore issued an appeal for information from the public and for any potential witnesses who were in either area during specific times. It is vital that anyone who has any information shares with us it as soon as possible.” Earlier, he released a statement saying: “I know that this news will cause significant and understandable concern and is an unprecedented event in our city which has shocked us all. Police have launched a triple murder investigation after three men in their 80s were killed in similar circumstances and found within a mile and a half of one another. A 27-year-old man has been arrested on suspicion of murder after the bodies of the victims were discovered in two properties in Exeter in the space of 22 hours, Devon and Cornwall Police said.The deaths of the three men, one aged 80 and two aged 84, showed “similar injuries” and “similar levels of violence”, according to police, who said the way the bodies were “presented” led them to believe the three murders are linked. Police said the deaths were “unprecedented in the city” and admitted it had “shocked us all”. The body of an 80-year-old man was found at an address in Bonhay Road at around 3pm on Monday a house near St David’s Railway Station in Exeter – a busy road which runs north from the town centre to the station, parallel to the River Exe.While the house remains behind a police cordon, a handwritten note stuck to the front door reads: “Elderly man, 80 years of age, wants accommodation for himself and his pet cat.” He asks for any replies to be posted through his letterbox.
