The attempts by IS militants to kidnap several state leaders, are believed aimed at raising funds to spread and expand their ideologies.

Deputy inspector-general of police Noor Rashid Ibrahim said the police believed the group was willing to do anything to achieve that goal.

"The threat by IS is serious, and the police will fight the group wherever they are, to ensure they do not spread propaganda in this country," he told reporters in Kuala Kubu Baru, today.

He also assured that the country remained safe and secure, and the police were enhancing efforts to monitor the group.

On Tuesday, Deputy Prime Minister Ahmad Zahid Hamidi - who is also home minister - revealed that besides Prime Minister Najib Abdul Razak, Defence Minister Hishammuddin Hussein and himself, were also being targeted by the group.

Commenting on the experiment materials which were thought to be bombs at Aquaria, Kuala Lumpur Convention Centre (KLCC) on Wednesday, he said the students who left the objects in question, had no malicious intentions.

According to him, the police always tried to ensure public places and iconic locations in the country were well monitored.

Earlier, he attended a passing out parade for the Police Basic Training Programme, Cadet Sergeants Series 1/2015, at Maktab PDRM Kuala Kubu Baru, near Kuala Kubu Baru.

At the event, a total of 491 cadets - comprising 387 men and 104 women - successfully completed their nine-month training session.
