Imran Khan arrested in connection with attack on Pakistan Army headquarters on May 9
An anti-terrorism court (ATC) in Rawalpindi had summoned the Pakistan Tehreek-e-Insaf (PTI) founder, who is already behind bars in cipher and graft cases, in May 9 cases on Tuesday. However, Khan attended the court's proceedings via video link as he could not be produced in the court by Adiala jail authorities owing to security concerns.
