Meminaj, of Rouen Road, Norwich, was arrested following the incidents between 4pm and 6pm on June 23.

Appearing in custody at Norwich Crown Court he pleaded guilty to robbery and attempted robbery and having a knife.

He ordered prosecutors to obtain victim impact statements to assess the harm and probation service to compile an “all-options” report to assess his dangerousness. 

The court was told Meminaj had been released on licence from a period in youth detention shortly before the robberies after being deemed as not posing a risk.

It followed an incident in October 2022 when he had taken over the Great Yarmouth home of a vulnerable 61-year-old woman to supply cocaine and heroin.

On that occasion he and another man had jumped out of the window to try and escape police but had been arrested after surrendering to officers with tasers.

Meminaj, who was just 18 at the time of the offences, had been sentenced to three years detention in a Young Offenders Institution after the judge heard he had “played a significant role in the operation".
