A 999 call has been played to murder trial jurors, with a bar worker pleading for help as violence erupted at a Great Yarmouth pub.

Ian Church, 40, suffered a fatal brain injury after he was attacked by a group of people outside the Bricklayers Arms, in Great Yarmouth, on May 5, 2012.

Norwich Crown Court has heard that three people have already been convicted of the murder of Mr Church and now a fourth person Stuart Layden, 33, from Harlow, Essex, has also gone on trial for his alleged involvement in the attack. He has denied murder.

The 999 call played to jurors was made after windows were smashed at the pub in Nelson Road Central, and the call was made by Stephen Ryan, the brother of the licensee Damian Ryan.

In the call, in which screaming can be heard in the background, Mr Ryan tells the operator that customers in the pub were 'panicking and angry' about the windows getting smashed and said a man armed with a machete was also outside the pub.

Asked if anyone had tried to calm the man down he replied: 'We've got several people out the front trying to disarm him.'

He then tells the operator that the man has been disarmed and after finding out that Mr Church was lying in the road he said: 'One of our regulars got caught up in this.'

He tells the operator that his brother was performing CPR on Mr Church, but said he was 'out cold' and not breathing'.

The call ends when police and an ambulance team arrive on the scene.

He agreed with defence barrister Graham Parkins QC, that the whole thing had been a 'shocking and distressing experience' and accepted that no one at the pub had prevented him from making the 999 call to emergency services.

The trial continues.
