MDMK Chief Vaiko was on Friday stopped at Kuala Lumpur Airport and was denied entry into Malaysia. He was also questioned for several hours over his alleged links with LTTE.
Malaysian state Penang's deputy CM Ramasamy Palanisamy had invited Vaiko to attend his daughter's wedding on June 10.
On April 3, Vaiko was sent to 15 days judicial custody by a Chennai court for speaking in favour of Liberation Tigers of Tamil Eelam (LTTE) in 2009.
Vaiko had surrendered before the court and refused to apply for bail. Hence, the magistrate had to remand a judicial custody.
In 2009, the Chennai police had booked him for charges including the Section 124 A (sedition) and 13(1)b of the Unlawful Activities (Prevention) Amendment Act, 2004.
