The Devon and Cornwall police now believe that three incidents in Exeter are related.

The deaths of three elderly men in the city are all treated as suspicious.

Three bodies were discovered in two properties this week, and the investigations have now been formally linked.

A man was arrested in connection with the incidents.

What do we know so far?

The police were summoned to an address on Bonhay Road around 3:00 pm on Monday, February 11, after a man's body had been discovered in the address.

The 80-year-old man was declared dead at the scene. There are still inquiries to inform his family.

The next day at 1 pm, the police were called to an estate on Cowick Lane after the bodies of two 84-year-old men were at the address.

They were both confirmed as having died on the scene and their families were informed.

On Tuesday, February 12, police arrested a 27-year-old man on suspicion of murder. He remains in police custody at this time.

"I know that this message will raise significant and understandable concern and is an unprecedented event in our city that has shocked us all, and I know that all immediate thoughts will be with the family and friends of these gentlemen and you we can offer them as much support as we can.

"The investigation will be led by our Major Crime Investigation team, assisted by local detectives, forensics, family liaison officers, and numerous other specialists who have been working around the clock since Monday afternoon.

"The residents of Bonhay Road and Cowick Lane will continue to see police raids today as we continue their important work, and the local neighborhood team will walk over the next few days to provide advice, support and answers to questions.

"Although a man has been arrested for suspected murder in connection with these incidents, we must remain open-minded and avoid speculation, as we are still at a very early stage of an already complex investigation.

"We asked for information from the public and possible witnesses who were in one of the areas at certain times, and it is important that anyone with information share this information with us as soon as possible."
