A 17-year-old male, believed to be teen blogger Amos Yee, is under investigation for allegedly making offensive remarks about religion online.

The police confirmed in a statement yesterday that police reports have been lodged against a male Singaporean, 17, in connection with certain "religiously offensive remarks" posted online.

Amos first drew flak when he uploaded an expletive-laden video on March 27, four days after the death of Mr Lee Kuan Yew, when he compared the founding Prime Minister to Jesus Christ, saying that they were both as "power hungry and malicious".

He later posted an obscene image on his blog, featuring the faces of Mr Lee and former British premier Margaret Thatcher.

Amos was convicted on May 12 and found guilty of wounding the feelings of Christians in a video as well as uploading an obscene image onto his blog.

He spent about 50 days in remand as he repeatedly breached his bail conditions.

Amos was sentenced on July 6 to four weeks' jail. But he was released on the day that he was sentenced as the punishment was backdated to include his time in remand.

Since then, he has uploaded several posts on his blog.

In one of his latest posts, on Nov 27, Amos made reference to Islam as he shared his thoughts about former Nominated MP Calvin Cheng, who had caused controversy by making comments online about killing the children of terrorists.
