Puzzled by the lack of arrest and apparent police inaction over the matter, Malay rights advocacy group Perkasa is repeating a police report that it lodged precisely a year ago over social media rumours that a church on Jalan Raja Laut was torched in December 2014.

"It is weird that when people slander the PM arrests are made, but when there are those that insult Islam, there are no arrests," said Perkasa Youth leader Irwan Fahmi Idris, adding that the police report will be made at the Dang Wangi District Police Headquarters at around 3pm today.
