KUALA LUMPUR, Sept 22 (AFP) - Malaysian police on Tuesday put up a roadblock outside the home of detained former deputy premier Anwar Ibrahim where his wife, Wan Azizah Wan Ismail, is now leading the reform movement.

More than 100 riot squad officers were present when the barricade was started but most left soon after leaving around 20 to man the blockade.

No-one can now get through to the home in the west of Kuala Lumpur without passing through the barricade.

Azizah has already been told not to speak at public rallies, though she has vowed to continue speaking to journalists to defend her husband.

The 46-year-old mother-of-six also faces a police investigation over an interview in which she raised fears for his life.

Anwar was detained on Sunday when police stormed the home. He is now being held under a law allowing for detention without trial.
