"The protest was led by the state general secretary of the BJP youth wing and I was also part of it," senior BJP leader Yudhvir Sethi said.
Terming Masarat Alam as anti-national who would further fuel militancy in Jammu and Kashmir, the protesters demanded his immediate arrest.
"We will never tolerate the release of an anti-national leader who is a threat to the national security," a protester said.
Meanwhile, questioning the decision of the BJP-PDP state government to release the separatist leader instrumental in triggering 2010 stone pelting agitation, Congress asked Prime Minister Narendra Modi, Union Home Minister Rajanth Singh and RSS to clarify their stand on release of Masarat.
"The Prime Minister, Union Home Minister, RSS besides MoS in PMO Dr Jitendra Singh and Deputy Chief Minister Nirmal Singh, who belongs to Jammu region, should clarify their stand on the Masarat issue," Jammu and Kashmir Pradesh Congress Committee (JKPCC) Chief Spokesman and MLC Ravinder Sharma told reporters here.
