Law and Home Affairs Minister K Shanmugam said he will not be taking action against the two sisters who disrupted his Meet-The-People Session. On Mar 12, the pair had disrupted Mr Shanmugam's engagement with his Chong Pang residents with shouts and offensive signs. They also called him a liar. Mr Shanmugam also revealed that the duo is being investigated for unrelated offences but declined to provide further details. Nicolas Ng reports.
