The Education Ministry will investigate the background of a video showing a boy and a girl, both in secondary school uniform, which went viral on the social site since yesterday.

Deputy Minister P. Kamalanathan said he was disappointed with the students' behaviour although he had not seen the 15-second video.

"I heard about it from a source and I feel I must view it soon to facilitate the investigation," he told reporters after visiting SMK Pasir Gudang 3 here today to observe the SPM examination.

Kamalanathan said the ministry has yet to be able to identify the location of the video recording and hoped those with information could come forward to assist.

"We can only determine the kind of action to be taken against the two students after that," said the Hulu Selangor MP.

On another development, Kamalanathan said he was satisfied with the process of the SPM examination nationwide as careful preparations had been made, and so far, there were no complaints received concerning the question papers.
