The news was celebrated by hundreds of Khan’s supporters, who rallied outside an anti-terrorism court in the capital, Islamabad, where a heavy security presence was held for the ousted leader’s arrival.
The court extended Khan’s pre-arrest bail till September 1, which means he cannot be arrested before that.
Police launched an investigation this week after vowing “action” against the police chief and a magistrate during a speech in the capital on Saturday.
Khan said, “Listen Director General (Police), we will not let you go, we are going to file a case against you. And madam magistrate, you also get ready, we will take action against you.” Told his supporters during a rally in support of his former Chief of Staff Shahbaz Gill.
Gill was arrested earlier this month on sedition charges after he urged soldiers to disobey orders from military leaders.
Khan has alleged that the police tortured Gill while in custody and the claims among his supporters have gained strength. The Islamabad Police has denied Khan’s allegations.
Tensions have escalated between Khan and the ruling coalition government led by Prime Minister Shahbaz Sharif since the former star cricketer was ousted in a parliamentary no-confidence motion in April.
Khan has claimed that there is a US-led conspiracy against Sharif and the Pakistani military, accusing him of working with Washington to topple his government. The United States, Sharif and the Pakistani military have all denied the allegations.
But Khan’s claims have struck a chord with a younger population in a country where anti-American sentiment is common and anger at the establishment over rising cost woes.
His enduring popularity has translated into recent provincial election victories for his party and he has repeatedly called for a new parliamentary vote at mass rallies held since his expulsion.
