Police have released a recording of a 999 call made by a teenager who falsely claimed a bomb would go off in a Norwich shopping centre.
18-year-old Luke Brown was sentenced to six months in a young offenders' institution after causing a bomb hoax at Castle Mall food court on Thursday 6 March.
Remarkably, he carried out the hoax so that his brother, who worked in Burger King, could leave work early.
During the 14-minute call, Brown claimed that he was sent a letter issuing a bomb threat.

When questioned where the letter had gone, Brown said that he had "burnt it".
The call resulted in nine officers, including a dog handler, two PCSOs and a crime scene investigator being deployed.
The call was traced to a phone box on Long John Hill where Brown was arrested.
