"We have moved the court seeking issuance of Letters Rogatory (LR) to attach some properties of Naik, which we have identified in Malaysia," special ED Counsel Hiten Venegaonkar was quoted by India Today as saying.
Letters Rogatory are formal request from a court in a country to a foreign court for judicial assistance.
The ED moved the special Prevention of Money Laundering Act (PMLA) court last week, the portal reported.
Naik has been accused of spreading hatred through his provocative speeches, funding terrorists and laundering several crores of rupees over the years. The court had in April issued a non-bailable warrant against Naik in connection with the money laundering case.
The preacher fled India following an attack on a cafe in Bangladesh in July last year in which 22 people were killed. One of the terrorist suspects said he had been influenced by Naik's speeches.
Naik has denied any involvement with terrorists or that he promotes terrorism. He has Malaysian permanent resident status.
