Imran Khan is facing a string of anti-terror charges for allegedly making threats towards state officials.
The cricketer-turned-politician was ousted from power in April and has since been a critic of Pakistan’s new government and army.
He is accusing the government of temporarily blocking YouTube, so people could not watch his recent political rally.
At the rally, Khan promised to sue police officers for allegedly detaining and torturing one of his close aides.
If he is convicted, Khan could face several years in prison.
Meanwhile, his supporters are reportedly ready to take further actions if the former leader is arrested.
Authorities say he allegedly made threats against state officials.
