Inspector-general of police Khalid Abu Bakar today warned all rally organisers to abide by requirements under the Peaceful Assembly Act 2012 or face the music.

"This cannot go on... From now we will take sterner actions against them, including the ones burning candles at Dataran Merdeka.

"Don't think you just gather to burn candles so you do not need to give notice," Khalid said in reference to the nightly vigils held at Dataran Merdeka to call for Bersih chairperson Maria Chin Abdullah's release from detention.
