KUALA LUMPUR: A 34-year-old engineer was picked up in Terengganu to help in the Ujian Penilaian Sekolah Rendah (UPSR) examination leak investigations.
The man was arrested in a follow-up operation in Kemaman, Terengganu on Monday afternoon, thus making the total arrested so far to seven people.
Kuala Lumpur CID chief SAC Gan Kong Meng said police picked up the man at 1pm and was brought to Putrajaya.
He said the man will be produced in court to obtain a remand order.
Earlier, a headmaster was among four suspects remanded for four days by the Magistrates Court.
Two others were teachers and another is an insurance agent. All of them, aged between 30 and 50, were being remanded until Sept 18.
The suspects were being investigated under Section 8 (1) of the Official Secrets Act 1972 for possessing an official secret and communicate such information to others.
The Science Papers 018, 028 and 038, scheduled last Thursday, was postponed following a leak in the examination paper the day before.
Last Thursday, the UPSR English Papers 014/1 and 014/2 were also found to have been leaked, causing an uproar among the public.
The leak has forced 473,175 pupils from 8,384 schools nationwide to re-sit their Science and English papers on Sept 30.
Following the fiasco, Malaysian Examinations Board chief Dr Na'imah Ishak and deputy Dr Wan Ilias Wan Salleh have been suspended.
