The police will not protect those individuals or senior officers involved in leaking the Ujian Pencapaian Sekolah Rendah (UPSR) Science and English papers.

Home Minister Datuk Seri Dr Ahmad Zahid Hamidi said the police had opened an investigation paper and were liaising with the education ministry to jointly carry out a detailed probe into the leakages.

"More information will be unearthed by the police, especially on the method of distribution of question papers of not only UPSR, but also other examinations.

"The Education Ministry and the Malaysian Examinations Syndicate have given us much information to facilitate investigations.

"I wish to give my assurance that the police will not do a cover-up on an individual or senior officer involved in the leakage," he told reporters after opening the Batu Kawan Umno division delegates meeting here today.
