The death of a Lithuanian national in March – which led to a murder investigation – is no longer being treated as suspicious, police have confirmed.

Four people were arrested on suspicion of murdering Edmundas Tamosauskas at a house of multiple occupation (HMO) in Creek Road on April 18.

Police said the 42-year-old sustained “significant head trauma”, but the exact cause of death is still unknown.

Those arrested have been released with no further action to be taken.

A spokesperson for Cambridgeshire Police said: “This case has been deemed non-suspicious and passed to the coroner. The people who were arrested have been released with no further action.

“However, if the coroner’s file, which includes extra forensic testing, brings up anything of concern then this position can be reviewed.”

It was the second time in 18 months that police had discovered a body at the same house; in that instance the death, too, turned out to be non-suspicious

Dozens of police cordoned off the scene on the morning April 18 following the discovery of the body of Mr Tamosauskas..

A tenant said another man had died in the property in December 2016 and in that instance, too, there were no suspicious circumstances.

The housemate, who did not wish to be named, explained how he returned home to hear someone tell him:“There’s another one dead”.

He said: “I was out enjoying my day off yesterday when I came back at 9pm I couldn’t even park my car in the street because of all the police.

“Someone said ‘there’s another one dead’ because we had someone else die there in December 2016 in the same house. He was in his 40s too and was drinking until he passed out.

“I believe the latest man who died was working through an agency and maybe they have periods that are not as busy, so he was off work.

“I am not sure if the man was Lithuanian or Latvian but he did not speak English.”

Police swooped on the street last night, as neighbours said earlier this morning how “problems” had occurred at the property recently.

The housemate continued: “Yesterday there was a lot of drinking and people getting drunk.

“I have been living there for 18 months. It’s the cheapest rooms in March at £60 all inclusive a week.

“But most of the time the residents are just drinking. Five people officially live there but there can be up to seven or eight so I’ve complained to the landlord. He is a postman.”
