The Indra Gandhi Action Team (Ingat) has refused to budge over its claim that groups that are friendly to PAS have been helping to hide Indira Gandhi's daughter, who has been in the centre of a unilateral conversion and custody tussle.

This came after PAS deputy president Tuan Ibrahim Tuan Man yesterday denied the allegation and demanded an apology.

Ingat chairperson Arun Doraisamy, who had also claimed the involvement of preacher Zakir Naik and southern Thai separatist groups, said he would not withdraw his statement.

"Tuan Ibrahim got so defensive so fast before even asking us the justification (for our allegation).

"I doubt if he even tried to check on their NGOs within the state (PAS-led Kelantan) that is friendly to them or directly linked to them," he said in a statement today.

Arun claimed that Indira's daughter is presently studying in a non-registered religious school in Kelantan.

"Ingat would like to seek the cooperation of Kelantan state government to help us track the missing child to show they are sincere," he said.

Indira has been in a custody tussle with her ex-husband Muhammad Riduan Abdullah, who unilaterally converted her children to Islam and obtained custody of them through the Syariah courts.

This led to a lengthy legal battle between Riduan and Indira, involving both the syariah and civil courts.

Indira’s two eldest children now live with her, but the whereabouts of the youngest and her father remain unknown.

In 2014, the High Court issued an arrest warrant for Riduan but the police have yet to locate him.
