Listen to the 999 call and watch the video footage as six men are sentenced to 32 years in prison for a 'professionally planned' armed robbery at Winsor Bishop jewellers in Norwich.

The men were arrested within a hour of the raid on the London Street jewellers which caused £55,000 worth of damage and loss and prompted 40 999 calls from members of the public.

The robbers were all arrested just off the A11 near Thetford.

The six men, who are all from London, appeared at Norwich Crown Court today to be sentenced having all pleaded guilty to carrying out the robbery at the jewellers and stealing a quantity of watches on August 5, this year.

Judge Stephen Holt described it as a 'well planned and sophisticated robbery'.

He said the defendants were disguised and armed with weapons which 'must've presented a terrifying site to members of public on the street and to the security staff and those working inside'.

Judge Holt said he 'wouldn't be surprised if they (the staff) are still terrified today.'

The six defendants were sentenced to a total of 32 years in custody with:

Alfredo Rojasvargas, 24, from Islington, was jailed for six years.

Bradley McMillan, 22, from Islington, was jailed for six years.

Tommy McKenzie, 25, from Hillingdon, was jailed for six years.

Curtis Bradbury, 21, from Hillingdon, was sentenced to six years in custody with an extended five year licence period.

Mark Moloney, 18, from Islington, was sentenced to five years detention.

The sixth defendant, 17 year old had not previously been identified for legal reasons but has today been named as Dillon Zambon, from Islington, after Judge Holt lifted reporting restrictions on the youth. He was sentenced to three years detention.

Earlier the court heard from Chris Youell, prosecuting, who said it was a 'professionally planned commercial robbery' where they 'targeted' a 'high end' jewellers using both weapons and force.

He admitted it was 'largely unsuccessful' but said the gang got away with five watches worth £31,370.

The court heard the total loss to Winsor Bishop was £55,000.

Mr Youell said they had used various weapons, including a lump hammer, pick axe handle and axe, in the robbery and had injured two people.

A security guard was hurt after having an axe swung at him, causing a graze to his leg.

A man also received a facial injury after he was pushed by a member of the gang who had been hiding in a car port after fleeing the getaway van in Thetford.

Ian James, for McMillan, said his client would 'inevitably' receive a lengthy custodial sentence.

But Mr James said he was 'recruited' or 'brought in at a relatively late stage' and was not an 'organiser'.

He added that he had 'leant himself to an operation that would be terrifying' to those involved but did not expect anyone to be the victim of an assault.

Jonathan Morgans, for Bradbury, said his client made 'frank' admissions to police, had pleaded guilty at the first opportunity and had an 'absolute desire to change'.

He said he had written a letter which showed his client had 'insight leading to very full remorse.'

Eloise Emanuel, for the youth, said her client insisted he was a rider but did not take part in what went on inside the jewellers.

She said he had shown clear evidence of remorse and had suffered a particularly difficult time with the death of his grandfather in 2011 followed by the loss of five of his close friends - three of whom were murdered.

Michael Clare, for Rojasvargas, said it was a 'one off' with marked absence of professionalism.

He said: 'These young men could no more earn their living by robbing jewellery shops than Laurel and Hardy. They are incompetent, they are not professionals.'

He said his client was recruited and made 'the worst decision of his life' to get involved as his finances were in 'disarray'.

Mr Morgans, for McKenzie, said his client has spent time on remand reflecting on 'how others would've been affected' which was reflected in his guilty plea.

He said he was remorseful and that the offence was committed against a background of 'desperation' which led him to make a decision he will 'always regret'.

James Hasslacher, for Moloney, said it was not a professional crime.

He said his client was just 18 and had been recruited and agreed as he was in debt.
