 Osbourne left school at 15 and was employed as a construction site labourer, trainee plumber, apprentice toolmaker, car factory horn-tuner, and
abattoir worker. He attempted to commit burglary, stealing a television (which fell on him during his getaway and had to be abandoned), a handful of baby clothes (originally thought to be adult clothes as it was too dark to see when he committed the burglary, and which were stolen to sell to people at a pub), and some T-shirts.
 He spent six weeks in
Winson Green Prison when he was unable to pay a fine after being found guilty of robbing a clothes shop; to teach his son a lesson, his father refused to pay the fine.
