Prime Minister Datuk Seri Najib Tun Razak urged the people to heed the lessons learnt from the case of British paedophile Richard Huckle to prevent Malaysian children from becoming victims of paedophilia.

He said all parties must ensure that chilren are not exposed to situations where irresponsible people can take advantage of them.

"Those responsible for the care of children must be more careful and alert to prevent such sick activities from happening," Najib said on his Facebook.

The prime minister said he was angered and saddened to learn about the sexual violation of Malaysian children by Huckle.

The British paedophile was given 22 life sentences by a court in London for sexually violating 23 children and babies in Malaysia as well as children in Cambodia for almost a decade.

Reuters reported that Huckle, 30, would be in jail for at least 23 years for the crimes he committed on children aged between six months and 12 years from poor families in Kuala Lumpur.

Huckle pleaded guilty to 71 offences and police found more than 20,000 pornographic images of children in his computer and camera when he was arrested at Gatwick Airport in London in 2014.

Recently, British media reported that Huckle, a freelance photographer, had abused up to 200 children aged from six months to 12 years from 2006 to 2014.
