A New Delhi court has issued arrest warrants for Malaysian tycoon T Ananda Krishnan and his aide Augustus Ralph Marshall and is seeking Interpol assistance on the matter.

According to The Times of India, the court yesterday said the arrests warrants were necessary because Malaysia had not provided assistance over the past two years.

"They (Marshall and Krishnan) could not be served with the summons through the normal course by resorting to mutual legal assistance treaty between the two countries.

"Malaysian authorities have categorically declined to effect the service. In such a situation, the only way left is to approach the Interpol and for that issue of warrant is necessary...

"In such a situation when further issuance of summons would be a futile exercise, it is rightful for the prosecution to ask for warrant of arrest against the accused," the court was reported saying.

In 2014, India's Central Bureau of Investigation filed charges against the duo and South Indian politician and former Indian telecommunications minister Dayanidhi Maran over alleged corruption to help the Maxis group take control of an Indian mobile phone carrier in 2006.

The charges fall under section 120-B (criminal conspiracy) of the Indian Penal Code and under relevant provisions of the Indian Prevention of Corruption Act.

At the court yesterday, the judge also ordered the trial against the Maran brothers and the two accused companies - Sun Direct TV Pvt Ltd and South Asia Entertainment Holdings Ltd - be separated from that of Krishnan and Marshall's along with the two Malaysian companies involved, Astro All Asia Network Plc and Maxis Communications Berhad, to avoid further delays.

Last month Amanah Youth lamented the authorities' failure to follow up with India's call for assistance.
