17-year old Amos Yee was arrested by Singapore police on Sunday.
The former child actor and Zhonghua Secondary School alumni posted a 8-minute Youtube video last week which disparaged Lee Kuan Yew's career and make insensitive remarks about Christianity. He also called Lee Hsien Loong a "motherf**ker" and challenged him to sue.
More than 20 police reports have been made against Amos Yee since the video went viral.
On 28 March, Amos Yee uploaded an obscene image of Lee Kuan Yew and Margaret Thatcher onto his blog. The blog post has been taken offline.
Sengkang MP He Ting Ru said she was dismayed that many Singaporeans are living with racism. "There is no place in our society for racism, sexism or xenophobia," she wrote.
