British pop star pedophile Gary Glitter, known for his decades-long string of sex crimes involving young girls, is reportedly "on his last legs" behind bars in a UK prison. The 81-year-old former pop star, whose real name is Paul Gadd, is barely able to move, almost completely deaf, and increasingly isolated. He spends up to 23 hours a day alone in his cell on a unit reserved for vulnerable inmates. Despite his frail appearance, Glitter has not received any sympathy from fellow inmates, who view him as arrogant and raise tensions within the general population. He is currently serving a 16-year sentence for abusing three young girls.
