A team of private investigators has been hired to track down M Indira Gandhi's ex-husband Muhammad Riduan Abdullah, who abducted her daughter a decade ago.

“To support the efforts of the police, Indira Gandhi Action Team (Ingat) has hired a high-powered private investigator team to go hard in hunting for the fugitive.

“We will keep the police’s special task force informed of new developments, especially to assist us in arresting Riduan or for all trans-border investigative matters.

“We are positive we can close in on Riduan in a matter of weeks. It is better for him to surrender and come clean from all the mess and distress he has created,” Ingat chairperson Arun Doraisamy said in a statement today.

This follows Inspector-General of Police Abdul Hamid Bador earlier saying that police are doubling their efforts to find Indira’s daughter.

Arun also warned Riduan’s current wife or anyone from among his family and friends who may have information about his whereabouts against harbouring a fugitive.

Those who do so could potentially be implicated under Section 216 of the Penal Code, he said, which deals with those “harbouring an offender who has escaped from custody, or whose apprehension has been ordered.”

Arun (photo) claimed he has information which proves Riduan’s current wife is frequently in communication with him.

He added that there will also be a reward of RM10,000 to all taxis, Grab drivers, couriers, bus drivers and other commercial vehicle drivers with information leading to Riduan's arrest.

Ingat will also be holding a roadshow beginning in the middle of August in Penang, before moving onto Kelantan, Perak and elsewhere in Malaysia.

“Let me assure the public that Prasana Diksa will be returned to her mother Indira,” Arun said.

Riduan unilaterally converted his three children, including Prasana, to Islam in 2009.

A lengthy legal battle between Riduan and Indira had ensued, involving both the syariah and civil courts.

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

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

Last year, the Federal Court unanimously declared the children’s unilateral conversion to Islam to be unlawful.

In February, Ingat put up an RM10,000 reward for anyone who could provide information leading to Riduan’s arrest.
