Led by JKLF Vice President Bashir Ahmad Bhat, they courted arrest at Batmaloo locality of central Srinagar, officials said.
Prominent among those who courted arrest include sister and wife of JKLF leader Nazir Ahmad Sheikh who along with another senior party leader were awarded life imprisonment by a TADA court in Jammu last month, a JKLF spokesman said.
JKLF had launched "jail Bharo" agitation last week when its chairman Mohammad Yasin Malik courted arrest outside party headquarters at Maisuma in the heart of Srinagar on Friday.
