Police have identified a man in his 30s -who collapsed in a Wisbech park on Tuesday who died on Wednesday in hospital.

A police spokesman said: “We are currently dealing with the sudden death of a man who collapsed in Tillery Park, Wisbech, on Tuesday.

‘He was taken to Queen Elizabeth Hospital in Kings Lynn where sadly he died at just before 6pm on Wednesday.

‘A public appeal was made to identify the man and we would like to thank members of the media and public for their support with this appeal as through this we managed to trace a member of his family.

‘The death is being treated as unexplained and has been passed to the coroner’s office for a post mortem.’

Police visited pubs in Wisbech on Wednesday to try and put a name to the man whose Christian name they believe might be Martin.

A photo of the man was shown to customers and the search is being centred on areas of population where migrant workers socialise.

Police told customers that the man – admitted to the Queen Elizabeth hospital in Kings Lynn on Monday- only regained consciousness for a brief moment.

He is thought to have died from organ failure but the cause of death is yet to be officially confirmed.

The man was described as in his thirties, dark brown hair and around 5 foot 10 inches tall. He has tattoos on his arms and wrists.

A woman who met police on Wednesday in a local pub said she had been told the only information police have is that his name might be Martin.

She added: “I really want to find his relatives. A man needs to rest in peace and be buried by his family.”

The coroner for Cambridgeshire has been informed.
