An 82-year-old man with Alzheimer's was one of four people targeted by a pair of robbers during an early morning 90-minute Norwich crime spree.

The victim, who has since died, was walking along Aylsham Road when he was confronted by George Rivett, 19, and 20-year-old Dominic Gonzalez.

Norwich Crown Court heard the victim had been on the phone with his daughter when the pair approached him and shouted "give me the f******g money, we've got your man".

Edward Renvoize, prosecuting, said they stole a wallet and phone from the victim who was one of four targeted by the robbers in the early hours of January 25, last year.

Mr Renvoize said it started between 5am and 5.30am when they attempted to snatch a vape from a man who was walking along Prince of Wales Road.

Next, they encountered the elderly man with Alzheimer's whose daughter was "extremely distressed" and went on to say she felt as if her "heart stopped" as a result of what happened.

By 6am, a woman walking along Magdalen Street was approached by the pair who shouted "give us your money" before going through her pockets, although they were only able to find dog mess bags.

The pair next encountered a man on Prince of Wales Road who they shouted at and asked if he had any money.

He told them he had not but had his phone out which they took.

Police were called while the spree was going on and the pair were arrested by officers nearby.

In an interview with police, Rivett answered 'no comment' but Gonzalez said they had been drinking and decided they would "go out to try and rob people to get some money".

Rivett, of no fixed abode, and Gonzalez, of Jewson Road, Norwich appeared in court on Wednesday (September 6) having admitted two robberies and two attempted robberies.

Describing the offences as "abhorrent" Judge Anthony Bate sentenced Rivett to 30 months detention in a young offenders institution (YOI) and Gonzalez to two years in a YOI.

Oliver Haswell, for Rivett, said his client had "no recollection of events due to his use of illicit substances on the day in question" adding it happened following a "significant downturn in his mental health".

Juliet Donovan, for Gonzalez, said her client deserved credit for his pleas and was "mortified by what he had done".
