Deputy Prime Minister Muhyiddin Yassin said the authorities including the police, the Malaysian Communications and Multimedia Comission (MCMC) and the Attorney-General's Chambers must act speedily and firmly against individuals who commit sedition in the social media.

He said the enforcement of existing laws must also be strengthened to curb the crime of sedition spreading in society so as to ensure that the prevailing racial and religious harmony is not tarnished by these irrresponsible people.
