Two PKR leaders were today grilled by police over their role in the PKR de facto leader Anwar Ibrahim's 69th birthday party held outside Sungai Buloh Prison on Aug 10.

PKR communications director Fahmi Fadzil and PKR Youth information chief Lee Chean Chung were probed under the Peaceful Assembly Act 2012.

Before entering Sungai Buloh district police headquarter, the duo took a swipe at the police by holding a placard that read 'Jangan siasat siapa yang menyanyi, siasat and tangkap #MO1!' (Do not probe the one who sings, probe and arrest #MO1!).
