Datuk Seri Anwar Ibrahim has been admitted to Hospital Kuala Lumpur (HKL) to receive further medical treatment, just over a month after his first hospitalisation in June.
"He will be given intensive physiotherapy treatment for his shoulder pain, his blood pressure will be monitored, and he will undergo a CT scan on his kidneys," said PKR communications director Fahmi Fadzil in a statement on Tuesday.
He said that the former Opposition leader will be placed in a separate ward and is expected to stay in hospital for a few days.
"Datuk Seri Dr Wan Azizah Wan Ismail was also allowed to visit Anwar earlier in the afternoon," said Fahmi.
However, the statement did not say what state of health Anwar was in.
Anwar was last admitted to HKL in June to undergo a series of scheduled tests to investigate the source of blood in his stools. He was discharged from hospital four days later.
In May, Anwar's family and lawyers said that his health has been deteriorating since he was jailed.
His second daughter Nurul Nuha told the media that her father had lost up to 6kg, had blood in his stools, was suffering from high blood pressure and had shoulder pains.
Anwar was jailed in February for five years on charges that he sodomised former aide Mohd Saiful Bukhari Azlan in 2008, a case he claims was politically motivated.
