Four civilians were reported to have been killed by gunfire in the unrest, according to local media reports.
Thousands of protesters, led by Bushra Bibi, Mr. Khan’s wife, had gathered in the capital since Monday night.
They vowed to stage a sit-in at a major town square near important government buildings, demanding Mr. Khan’s release.
Since then, he has accused the powerful military of orchestrating his removal and has led a protest campaign to reclaim power through public rallies.
Mr. Khan’s party, Pakistan Tehreek-e-Insaf, claimed victory in the elections and accuses the current civilian government of being a puppet of the military.
