The Malaysian police will seek help from international agencies like Interpol and Europol to monitor the overseas activities of the Hindu Right Action Force, which spearheaded protests by ethnic Indians against alleged marginalisation.
Deputy Internal Security Minister Datuk Mohd Johari Baharom told reporters that the agencies involved were the European Law Enforcement Organisation, Asean police and Interpol.
The Malaysian police had earlier accused the Hindraf of having links with terror outfits, including the Liberation Tigers of Tamil Eelam.
"They are not only monitoring the group, but everything," he was quoted as saying in Kuching by Malaysian news agency Bernama.
Johari was commenting on reports of attempts by one of the leaders of the group, P Waytha Moorthy, to garner support abroad.
He said that the Malaysian police's good ties with international law enforcement agencies would enable the force to obtain more information on crime activities abroad.
On December 13, five Hidraf members were held under the Internal Security Act and sent to two-year detention.
They are P Uthayakumar, 46, M Manoharan, 46, R Kenghadharan, 40, V Ganabatirau, 34, and T Vasantha Kumar, 34.
