KUALA LUMPUR: The attack on the Ulu Tiram police station in Johor early today, which left two policemen dead and another injured, has shocked the nation.

The attacker, who was shot dead at the scene, was believed to be a member of the Jemaah Islamiyah (JI) group.

Inspector-General of Police Tan Sri Razarudin Husain said that so far, seven individuals had been detained, including two private higher education institution (IPT) students aged 21 and 22, as well as the 62-year-old father of the suspect, who is also a JI member.

He said preliminary investigations revealed that the suspect, who was shot dead after exchanging gunfire with the policemen, was suspected to have meticulously prepared for the attack.

In the 2.45 am incident, three people were confirmed dead, namely two 22-year-old police personnel and the 21-year-old suspect, while another policeman was injured.
