The man whose death following an assault outside a Norfolk pub has sparked a murder investigation has been named.

Michael O'Dwyer died in hospital on Sunday evening, following an incident outside the Red Lion in Dereham around 24 hours earlier.

Another man, Tyrone Busch, 40, was arrested on suspicion of murder while he was at another pub seven miles away, the Beeston Ploughshare on Wednesday evening.

He appeared at Norwich Magistrates' Court earlier today to be charged with Mr O'Dwyer's murder.

Meanwhile, a friend of both men has told of her shock at Mr O'Dwyer's death.

Georgia Jane, 20, said: "This has all been so intense. I can't get my head around what has happened."

She said the pair knew each other and had both been drinking in the Red Lion on Saturday evening.

Mr O'Dwyer, who was in his 30s, was able to go to his home in Dereham after the incident.

However, paramedics were called to the address at around 5am on Sunday after his condition deteriorated.

He was taken to the Norfolk and Norwich University Hospital, where he died hours later.

A post-mortem examination said the provisional cause of death was a traumatic head injury.

Friends have described Mr O'Dwyer - who was also known as Spooner - as "lovely" and "very sweet".

Police did not become aware of the death until Tuesday, at which point they launched an investigation which led them back to the Red Lion assault, and to the Beeston Ploughshare, where they arrested Busch.

Ms Jane said police had been to interview her as she knew both men and had seen Busch after the incident.

Busch gave an address in Hall Road, Norwich, when he appeared in court to be charged with Mr O'Dwyer's murder.

He wore a grey sweatshirt and spoke only to confirm his name, age and address.

He was remanded to custody as magistrates committed the case to Norwich Crown Court.

Police are appealing to the public for witnesses and anyone who may have information about the incident.

They should contact the Major Investigation Team quoting reference 36/52076/24.
