Lebanese judge Ghada Aoun Tuesday indefinitely extended a subpoena she had issued earlier this month for central bank governor Riad Salameh.
This came after Salameh failed to show up to an interrogation session on Tuesday, Aoun told Reuters.
Aoun has sought to interrogate Salameh as a witness in several cases alleging financial impropriety.
Salameh has denied any wrongdoing and has sought the dismissal of Aoun from investigations against him, alleging she is biased.
