Former Pakistani Prime Minister Imran Khan was arrested Tuesday at a court in the capital Islamabad by paramilitary officers. Footage of the arrest shows dozens of paramilitary personnel surrounding Khan and pushing him into an armored vehicle before driving him away.

Khan, who heads Pakistan Tehreek-e-Insaf (PTI), one of the country’s largest political parties, was at the Islamabad High Court to attend hearings for his bail applications concerning corruption cases against him, which he says are politically motivated. 

The arrest follows recent tense exchanges between Khan, the former national cricket captain who became Pakistan’s prime minister in 2018, and the country’s powerful army.

After surviving an assassination attempt last November, Khan accused a senior military officer and Pakistan’s current prime minister, Shehbaz Sharif, of being behind the attempt.

An army spokesperson censured Khan this week for “highly irresponsible and baseless allegations against a serving senior military officer without any evidence,” to which Khan replied via video statement Tuesday: “This is my army and my Pakistan. I don’t need to lie.”

The military spokesperson warned of legal action if Khan keeps up his accusations. Concerning the possibility of arrest, Khan said: “If someone has a warrant, they should directly bring it to me. Bring the warrant, my lawyer will be there. I’m ready to go to the jail myself.”

The PTI and supporters of Khan are calling for shutting down Pakistan, blocking roads and staging mass protests to demand his release.

“It’s your time, people of Pakistan. Khan has always stood for you, now its time to stand for him. #ReleaseImranKhan” one tweet from the PTI’s official page said, along with a graphic that read “SHUTDOWN PAKISTAN.”

The 70-year-old Khan, who remains hugely popular across the country of 230 million, was ousted from power in April 2022 after a no-confidence vote by opposition lawmakers alleging corruption and unconstitutional actions. The charges were backed up by the country’s Supreme Court.

In October, Pakistan’s election commission passed a ruling barring Khan from holding office again, sparking outrage among his many supporters who claim foul play.

Khan and his supporters said last year that his ousting was a conspiracy planned by Sharif and the United States, the latter of which has a long and complicated relationship with the Pakistani government. Sharif and Washington denied the accusations.

Khan’s legal troubles only seem to have made him more popular among his base, who believe he will make a comeback and become prime minister again in elections to be held later this year. Some political analysts see him as a likely favorite as well, and many expect the charges against him to be dropped.

Khan is one of the most famous figures in Pakistan and the wider South Asian region, known for leading Pakistan’s national cricket team to glory in the 1980s and ’90s. He later transitioned to politics, founding the PTI in 1996.

Khan’s political career was marked by losses until his party, running on a populist platform, won the most seats in Pakistan’s National Assembly in 2018 and he led the governing coalition as prime minister.

The White House said it was aware of Khan’s arrest and that it did not have a position on the matter and referred further queries to the government of Pakistan.
