A Singapore teenager who criticised Lee Kuan Yew on social media soon after the former leader's death has been arrested and will be charged with making "insensitive and disparaging" comments about Christians.

The case has reignited concerns about censorship in the Asian financial hub.

In a widely viewed YouTube video, Amos Yee celebrated the death of Singapore's founding father Lee, who died last week aged 91 and was cremated after a state funeral on Sunday.

Mr Yee also made insensitive remarks about Christianity in the video, which was seen by hundreds of thousands before it was taken down.

He faces charges of intentionally wounding the religious or racial feelings of another person or group and could face up to three years in jail

The Committee to Protect Journalists (CPJ) said it was concerned about the teenage blogger's arrest and called on authorities to release him immediately.

Singapore has tight rules on censorship, blocking dozens of websites and publications ranging from Playboy magazine to some children's books and comics.
