Khan’s arrest and three-day detention in connection with the same case in May sparked deadly violence when thousands of his supporters took to the streets and clashed with police.
Following his release, PTI was targeted with reports of thousands of arrests, intimidation, and a clampdown on the press.
Khan was prime minister until April last year, when he was ousted in a no-confidence vote he says was orchestrated by the country’s powerful military.
He said, “My only request and appeal is that you should not sit quietly at home.”
“This is a fight for justice, for your rights, for your freedom… Chains don’t just fall, they have to be broken. You should continue the peaceful protest till you get your rights.
But party officials said on Sunday there were no plans to call for nationwide protests.
“As far as the protest is concerned, it is not a planned one as the protesters were raided and detained by the police yesterday,” said an official on condition of anonymity.
Following Khan’s arrest, police were deployed at major centers across the country and swift action was taken to disperse the mob of PTI supporters.
