After a Madonna fan was sentenced to be detained indefinitely after breaking into the singer's London home, we consider the most famous cases of celebrity stalking.
After writing "M, the universe brought us together in 1992 and again this year in Prague. Meet me please" outside Madonna's New York apartment building, retired fireman Robert Linhart was arrested. He was eventually released on bail for £12,000 after he denied resisting arrest and weapons possession, while his lawyers argued he was merely a fan.
But of course, this isn't the first time that Madonna's had to deal with unwanted fan attention.
In 1996, another Robert, this time a Hoskins, was sent to jail for 10 years after stalking and making violent threats against Madonna. Homeless Hoskins had been arrested the year before after he claimed the Material Girl was his wife, and threatened to slice her throat from ear to ear. He also threatened to kill her bodyguards for coming between them, and at one point actually managed to get within 10 feet of her after scaling the wall of her LA home. On his third attempt he was shot and wounded in a scuffle with guards. He continued hounding her from prison and wrote 'Madonna's stalker' on the walls of his cell. Hoskins prison time was up in 2006, and there've been no reports of him pestering the star since.
