A Melbourne man kidnapped a fellow ice addict and threatened he would "send parts of his body home" over a drug debt.
Mark Andrew Brown's victim was in a hotel room when he was woken and accosted on October 26 last year.
Over a 12-hour period, Brown punched the 26-year-old and threatened to "go knocking" on his parents' door.
During the ordeal, the victim phoned his parents saying he needed $5000 and the amount would go up every day unless it was paid.
His father screamed on the phone to let his son go, refused to pay the ransom, and called police.
Brown was handed almost four years behind bars in the Victorian County Court on Wednesday, by the same judge who earlier spared him jail for "remarkably" similar crimes.
"His ongoing addiction to drugs and his recourse to crimes continues, despite the merciful opportunities given to him," Judge Michael McInerney said.
Brown, of Kingsville, met his victim just a couple of weeks before the offending, when he gave the man drugs to sell.
He had been released from jail four months earlier, and was on a community corrections order when he committed the crimes.
Brown wrote a letter to the court, expressing remorse and saying he was drug free, but Judge McInerney viewed it sceptically.
"Unfortunately, that is exactly what he put to the court on the occasion I granted him a CCO," he said.
Brown pleaded guilty to assault, false imprisonment and extortion with threat to inflict serious injury.
He was sentenced to five and a half years in prison and ordered to serve three years and eight months before he is eligible for parole.
An additional three months was added to that, because Brown breached the CCO.
