Former minister P Waythamoorthy has lambasted the remand extension of radio personality Patrick Teoh, calling it a "return of the dark old regime where abuses of powers by police went unchecked".

Teoh was remanded following his arrest in Petaling Jaya, Selangor on May 9 to facilitate investigations into his allegedly insulting remarks about the Tunku Mahkota of Johor Tunku Ismail Sultan Ibrahim.
