Two gun-wielding “gangsters” jailed after storming a house in Amersham before firing a shot and attacking the people inside have had their sentences slashed by top judges.

Violent criminals Garfield Mushore, of Albert Road, Luton, and Krystal Glasgow, of Holly Drive, Aylesbury were armed with imitation handguns and a knife when they raided the Hill Way property on January 2 last year.

Once inside they attacked the occupants – a 38-year-old woman and two men aged 25 and 45 – before shooting at them and hitting one of them round the head with the gun as well as beating them.

The pair attempted to take a television but failed and then fled the scene.

Twenty-year-old Mushore was convicted of aggravated burglary while Glasgow, 19, admitted the same crime.

Both men were told at the time they will be deported from the UK after serving their jail terms.

The judge who sentenced them said they had been “acting like gangsters”, while in a hearing this week, Mrs Justice McGowan said the victims must have been “profoundly upset” by the “terrifying” experience.

Nadia Chbat, barrister for both men, argued their sentences were far too tough, especially considering their youth.

Mrs Justice McGowan agreed their punishments were “too great”.

The judge, who was sitting with Lord Justice Davis and Mrs Justice McGowan, reduced Mushore's sentence from 12 to nine years.

Glasgow's term went down from eight years to six.
