Former Pakistan Prime Minister Imran Khan, who was arrested by Rangers from outside Islamabad High Court on Tuesday, told his supporters in a pre-recorded video that he will be "closed inside in an unlawful case" and that he "may not get chance to address them again".

"My fellow Pakistanis, when these words of mine reach you I will already be closed inside in an unlawful case. After this, you all should realise that fundamental rights, law and democracy have been buried. Maybe it is possible that I won't get a chance to talk to you again," Khan said in the pre-recorded video that came out after his arrest.
