A WIDESPEAD videoclip, purportedly showing two children engaging in sexual acts, has caused shock and concern among parents, reported Harian Metro.

The 30-minute clip titled "Budak-Budak Pun Dah Pandai Sekarang (Even Children Are Well Informed Now)" has been circulating on the Internet and via mobile phones.

A boy and a girl - believed to be around eight years of age - are seen in the clip stripping off their clothes and kissing each other, the paper reported.

Their acts are believed to have taken place on top of an abandoned building, where it was filmed.

The Malay daily in its front-page story, however, said it could not be ascertained if the children were locals.

The clip was made known after several concerned parents called the newspaper expressing their worries.
