Disgraced British rocker Gary Glitter has been admitted to hospital after suffering a heart attack. The 1970s star - who was diagnosed with high blood pressure last year (07) - collapsed last Sunday (13Jan08) in the dormitory he shares with 18 other inmates in a Vietnam prison. He is serving a three-year sentence after being convicted in 2006 of committing obscene acts with two Vietnamese girls, aged 11 and 12. The singer - real name Paul Gadd - was due for release in August (08) but is now being considered for an early release so he can seek specialist care in the U.K. A nurse tells British newspaper The News Of The World, "Mr Gadd suffered a heart attack. He remains very frail and his blood pressure is still dangerously high. When he is well enough he will go back to prison but at the moment he is still a very sick man."
