The arrest of PTI chairman Imran Khan also affected the Pakistan stock market as the benchmark KSE-100 witnessed a decrease of nearly 500 points.
The former prime minister was arrested from the premises of the Islamabad High Court on Tuesday by the Rangers personnel in the Al Qadir Trust case.
At around 2:40pm, the benchmark index was being traded at 41,358.37, a decrease of 471.12 points or 1.13%.
Experts attributed the sudden decline to the arrest of the former prime minister.
Initial reports suggested PTI workers were also involved in a scuffle with the law enforcement agencies and many were injured.
The Islamabad police confirmed the arrest in a tweet. The police added that he was shifted to the NAB office in Rawalpindi.
The Islamabad police IG described the conditions as “normal”, adding that Section 144 was in force and action would be taken in case of violation.
