"We also staged a sit-in over the issue of missing persons in the past and I hope our demands would be met," he said.
Earlier, MQM leader Kanwar Naveed Jameel had announced to shift the party's ongoing sit-in from Karachi Press Club to Chief Minister House.
The MQM leaders have been staging a sit-in since Saturday against what they called illegal arrests of the party workers and non-arrest of the workers' killers.
