Jonathan Nelson was caught selling the Class A drug shortly after the 'Cannonball' band's victory in December, but was branded a mere "delivery boy" by the defence during sentencing at Southend Crown Court yesterday (June 28).
Jonathan explained under oath that his cocaine habit resulted in him owing £3,000 to an individual known as Mr Turner, who threatened to abduct Jesy unless he settled the debt.
"He was making threats and he threatened to kidnap my sister because she had just become famous," the Daily Mail quotes him as saying.
"I said if there is anything I can do to pay the money I would do it. He called me again and said, 'You will have to do me a few favours'."
Judge Jonathan Black branded the 23-year-old's actions "stupid" and told him that the case "will no doubt cause embarrassment to your sister".
He received a 10-month prison sentence suspended for 18 months and 200 hours of community service, and was ordered to pay costs of £600.
