Protests have erupted in Pakistani cities after former Prime Minister Imran Khan was arrested as he appeared in a court in the capital, Islamabad, to face corruption allegations.

Pakistan Tehreek-e-Insaf (PTI) party urged supporters to take to the streets and thousands of Khan’s supporters took to the streets in the capital Islamabad, Karachi, Lahore, Peshawar and other cities to protest against his arrest.Since his removal from power last year, Khan has been slapped with dozens of charges, which he denies and says are politically motivated.

“Imran Khan has been arrested in the Qadir Trust case,” the Islamabad police said on its official Twitter account, referring to a corruption case.
