Four suspected senior leaders of the Tamil Tigers were detained in multiple raids on Thursday.
The suspected leaders of the LTTE were apprehended by the Bukit Aman Special Branch Counter Terrorism Division following raids in Kuala Lumpur and Selangor.
Speaking to Malaysian media, Inspector-General of Police Tan Sri Khalid Abu Bakar said one of the suspects was a bomb expert holding the UNHCR refugee card while another was suspected of an attempt to assasinate former Sri Lankan president Chandrika Kumaratunga in 1999.
"The third suspect was an accomplice in an earlier thwarted terror attack in India.
He added among items seized were a high number of forged passports along the official seal of Malaysian Immigration department and other countries.
"We are finding it problematic that among 14 LTTE members arrested this year, seven were using UNHCR cards.
"We will get to the bottom of this," he said.
