Violence has broken out after Pakistan's former prime minister Imran Khan was dragged out of court and arrested, following an appearance in the country's capital city to face multiple corruption cases.
Fawad Chaudhry, a senior official with the Pakistan Tehreek-e-Insaf (PTI) party, said the 71-year-old was arrested in Islamabad on Tuesday by agents from the country's anti-corruption body, the National Accountability Bureau.
Later on Tuesday, the PTI called on supporters to "shut down Pakistan," tweeting: "It's your time, people of Pakistan. "Khan has always stood for you; now its time to stand for him."
