An attendant at the Shell petrol station in Normanston Drive in Oulton Broad was so frightened during the incident that she locked herself in the premises, Ipswich Crown Court heard.

Sentencing 21-year-old Kieran Dwayne to 12 months in jail, Judge Rupert Overbury described the knife as 'massive' and said it was 'sheer luck' no-one was seriously injured.

He said that witnesses described Dwayne as behaving extremely aggressively and getting out of his car as if he was going to attack someone.

'It is plain you were trying to get at your brother,' said the judge.

'Knife crime is on the increase nationally and it is certainly on the increase locally. The courts have a duty to protect the public from people who walk round with knives,' he added.

Dwayne, of Victoria Terrace, Lowestoft, admitted threatening a person with a blade in a public place on August 9.

Lynne Shirley, prosecuting said members of Dwayne's family, including his brother and aunt, had gone to the garage forecourt out of concern for him.

The defendant had got out of the passenger seat of his friend's car and was seen to produce a 'Rambo -style' knife and approach his brother.

His aunt tried to get between the brothers and was shouting: 'No. No' and he was described as waving the knife at his brother and shouting and swearing.

The incident ended with Kieran Dwayne walking off and he was arrested five days later.

He told police he thought his brother had attacked him but he accepted this wasn't the case. He also told officers he had not been taking his bipolar medication.

Folishade Abiodun, for Dwayne, said her client was ashamed of the way he had acted towards members of his family.

She said he had been diagnosed with bipolar disorder, anxiety and depression and had been using Class A drugs, including cocaine.

'He began to lose a handle on reality and life in general. He hadn't slept for a week and had been binging on alcohol and drugs,' said Miss Abiodun.

'He felt his family had ambushed him and he was trying to get away,' she added.
