A Pakistani court on Monday extended former Prime Minister Imran Khan's pre-arrest bail for eight more days on terrorism charges relating to a speech in which he allegedly threatened police and judicial officers, his lawyer said.

Khan, who appeared in court in person, was booked in the case by police in August. This is the fourth time he has secured prearrest bail in the matter.

"Bail is extended till September 20 with the same sureties," Khan's lawyer, Babar Awan, told Reuters.
