AYS activists also burnt effigies of Prime Minister Manmohan Singh in Guwahati.
"The Prime Minister has been representing Assam for years in the Rajya Sabha but when it comes to tackling the burning issues faced by the state he has failed to take any action," AYS president Shyamanta Kashyap told reporters here today.
Terming the recent violence in parts of lower Assam as "the result of unbridled immigration from Bangladesh," he said both the central and state government has remained mute over the years.
Kashyap said only a few thousand illegal immigrants have been detected and successfully deported from the state since the Assam Accord of 1985.
