Marumalarchi Dravida Munnetra Kazhagam Chief Vaiko was on Thursday arrested on the charge of making 'highly inflammatory speeches supporting the LTTE' [Images], police said.

This is the second time that Vaiko had been arrested for supporting the banned outfit. He was arrested under POTA by the previous All India Anna Dravida Munnetra Kazhagam government for speaking in support of the Liberation Tigers of Tamil Eelam.

Vaiko had at a public meeting in Chennai on Tuesday said a separate Tamil Eelam under the leadership of LTTE chief Prabhakaran would come into existence soon in Sri Lanka [Images].

"LTTE and Sri Lankan Tamils could not be separated. Though we are against any violence, we should differentiate between violence and right," he said.

"Prime Minister Manmohan Singh [Images], who had assured me no military aid would be supplied to Sri Lanka, had gone back on his word," he alleged.

Vaiko said, "if the need arises, I will be the first man to take up arms in support of Sri Lankan Tamils. I will gather youths all over the country for this purpose."

The MDMK presidium chairman, M Kannappan, had told the meeting that time would come to demand for a separate Tamil Nadu. In that meeting, a two-hour film on Sri Lankan army's alleged atrocities against Tamils was screened.

In a statement on Wednesday, AIADMK chief Jayalalithaa had demanded that all LTTE supporters be booked.

Tamil Nadu government's decision to arrest Vaiko was to make it clear that ruling DMK's support was only for the suffering Sri Lankan Tamils and not for LTTE.

Vaiko, now an ally of Jayalalithaa, was detained under POTA by her government in 2004 on his arrival from the United States after he had made a pro-LTTE speech at a public meeting in Tirumangalam in Madurai [Images].

DMK chief M Karunanidhi had condemned Vaiko's arrest at that time.
