Some 600 activists belonging to pro-Tamil Eelam outfits were arrested on Tuesday for allegedly attempting to march to the Defence Services Staff College at Wellington, 15 km from here, where two Sri Lankan defence personnel are undergoing training.
Protesting against the training, the activists demanded resignation of Defence Minister A K Antony for giving "false" assurance that no Sri Lankan military personnel would be given training on Tamil Nadu soil.
The activists shouted slogans against the central government, which, they alleged, was taking an anti-Tamil stand.
They also burnt the effigies of Congress president Sonia Gandhi and Sri Lankan President Mahinda Rajapaksa besides the Sri Lankan national flag.
Police said the activists were stopped some three km from the college and arrested.
Talking to reporters, K Ramakrishnan, General Secretary, Thanthai Periyar Dravida Kazhakam (TPDK), said like-minded parties and organisations have decided to stage demonstrations in front of Congress Offices in Tamil Nadu and also against Central Ministers from the state, dates for which would be announced later.
Besides TPDK, workers from Viduthalai Chiruthaigal Katchi, MDMK, Vanigar Sangham and Federation of Tamil National Students, participated in the demonstration, police said.
In a letter to Prime Minister Manmohan Singh recently, chief minister Jayalalithaa had slammed the Centre for being "insensitive" on the issue of training Sri Lankan defence personnel and asked it not to train them until Colombo takes satisfactory and credible action to end human rights violations against Tamils.
She had said two Lankan officers--Wing Commander MS Bandara Dassanayke and Major CS Harishchandra Hettiarachchige--were undergoing training at Wellington, which, she said, was a matter of "grave import that greatly offends the sensitivities and sentiments of people of Tamil Nadu."
