The party activists, led by its state unit chief Kamal Sharma, raised anti-Pak slogans and protested against the "brutal killing" of Sarabjit.
"Pakistan's action is devoid of any respect for basic human rights and asked the neighbouring country to stop giving shelter to the terrorists against India," party vice-president Rajinder Mohan Singh Chhina, who was also present on the occasion, said.
He also blamed the UPA government for its "weakness" to deal with hostile neighbours, and asked the Centre to show that it has strong will to protect its citizens from such brutalities.
Later, over 200 workers and leaders were detained at Gharinda Police station but were later released by the authorities.
