Paralysed gangster Yip Kai-foon was taken to hospital under heavy armed guard from Stanley Prison yesterday after complaining of a heart problem.
Yip, 37, told prison hospital doctors that his heart was beating 'very fast'.
A source said: 'Initial checks have found he was suffering from a urinary tract infection that probably made his heart beat faster.
'Further examinations are required to confirm whether he has a heart problem so we needed to send him to hospital. Apart from his suspected heart problem, he was fine.' Armed police escorted Yip to Queen Mary Hospital after 5pm, about four hours after he first complained of his problems.
Yip was once regarded as Hong Kong's most wanted man after making a daring escape from the same hospital in 1989, where he was receiving treatment while serving a prison term.
He was recaptured during a police shootout in Western in 1996 that left him wheelchair-bound.
