A pupil accused of posing as a social worker and kidnapping a baby twin is sticking to her alibi that she had an isiXhosa lesson at school at the time of the reported abduction, the Bellville Magistrate's Court heard during her bail application. The lawyer for 18-year-old Karabo Tau is so sure his client is innocent that he told the court he had obtained a letter from her teacher and CCTV footage to prove this. Sulaiman Chottia also asked baby Kwahlelwa's mother, Asanda Tiwane, which social welfare office the woman, who took her baby, claimed she was from. "She never told me. I never asked," said Tiwane. "I never thought of it your worship."Tau's family insists she is innocent, and an Instagram page called "FreeKarabo" has been set up to garner support for her. The court was packed for the bail hearing on Tuesday, with Tiwane speaking softly through an interpreter.

On the day her child was taken, January 16, the woman also wore sunglasses. Asked what she would do if a witness testified that Tau was actually at school and could not have taken the baby, Tiwane said simply: "There is nothing that I will do your worship, but what I know is that she took my child."Pressed on Tau's alibi, she said: "I just want my child." Tiwane was taken to task for initially making a mistake with the date of her child's disappearance but said although she had mixed the date up, it was very definitely a Thursday that her child was taken.
