Sejahratul Dursina @ Chomel Mohamad, wife of an alleged al-Qaeda operative, was to meet her mother and children at 3pm, her sister Suri Hanim told malaysiakini earlier.
However, when contacted later, Suri refused to comment.
Sejahratul, a 37-year-old IT company director, was detained for her alleged links to the Malaysian Mujahidin Group (KMM) which police say was bent on overthrowing the government through violence.
She was among 14 people arrested in a two-day police operation which begin on April 17.
Her husband, former army captain Yazid Sufaat was arrested last December for his alleged connections to the terrorists involved in the Sept 11 attacks on the United States s Al-Qaeda terror netowrk.
Also detained were Sejahratuls brother-in-law and Suris husband Ahmad Yani Ismail.
Both Yazid and Ahmad are being held for two years at the Kamunting Detention Centre in Kamunting, Perak.
Not safe
In a related matter, Keadilan Wanita earlier today urged the authorities to allow Sejahratul access to her family.
This is a matter of urgency because she is a woman and because no police lock-up is safe for women, said the wings deputy chief Irene Fernandez at a press conference in Petaling Jaya today.
Fernandez also urged the Malaysian Human Rights Commission (Suhakam) to visit Sejahratul and see how she is doing.
Four women were arrested and detained under the ISA in the 1987 Operasi Lalang.
They are Universiti Putra Malaysia retired assistant professor Dr Cecilia Ng, womens issues activist Lim Chin Chin, founder member of the Womens Development Centre (WDC) and All Womens Action Society (Awam) Dr Chee Heng Leng and Sahabat Wanitas Irene Xavier.
During a press conference held last year, the four relayed their experience under custody and claimed that they were subjected to physical torture and violent interrogation.
