The family of a former Cambridgeshire man whose mysterious death has triggered a murder investigation have described how the son, brother, uncle, nephew and boyfriend would be "sorely missed by all".

The body of Matthew Griggs was found by his girlfriend on a quiet lane on the outskirts of Norwich.

Four days earlier, the 38-year-old had been involved in two separate altercations in the city centre and police launched a murder investigation after a post mortem examination revealed he had suffered blunt force trauma to his chest.Wisbech Standard: Church Lane, Sprowston, where the body of Matthew Griggs was foundChurch Lane, Sprowston, where the body of Matthew Griggs was found (Image: Peter Walsh, Newsquest)In the weeks following the discovery of the body, at around 7.45am, on September 23, on Church Lane, Sprowston, officers arrested four men on suspicion of murder.

They all remain on police bail while the investigation continues.

Now, tributes to Mr Griggs, a former pupil at White Woman Lane Middle School and Sprowston High School, have been released by his family, who said they "still can't believe that he's no longer with us".

They said Mr Griggs, who did not have any children, was born in Norwich in 1985 and lived in Sprowston until the late 1990s when the family moved to Ely.

He later worked in several pubs, hotels and restaurants across the region.

He was a passionate Norwich City supporter and followed the club home and away, including a memorable trip to see the Canaries lose in the play-off final at the Millennium Stadium in 2002.

He was also a "very good cook", they said.

His family added: "Matthew was never happier than when he was in the kitchen preparing a meal (despite the kitchen being left like a bomb site when he had finished!). 

"These skills were often put to good use as he worked in various pubs, hotels and restaurants throughout East Anglia in the 2000s."

"He moved throughout the area in search of work and stability, including Mepal, March and Wisbech. 

"During his later years he moved to Great Yarmouth where he met his girlfriend. 

"Following a couple of years in Yarmouth, he returned to Norwich which he always said he felt most at home.

"I still can’t believe that he is no longer with us.

"How I miss his phone calls saying, “Hi Dad, it’s Matt”. 

"He is sorely missed by all."

The family said they wanted to thank Norfolk Police for their "commitment and hard work" over the past few months following the discovery of Mr Griggs' body.

The four arrested men had been bailed until April 3.

Three are in their 40s and one is in his 20s. They were all arrested in October.

Police believe Mr Griggs was involved in two altercations prior to his death and are particularly keen to hear from anyone who might have witnessed either.

The first was at Ketts Hill at about 7.40am on September 19.
