KUALA LUMPUR (THE STAR/ASIA NEWS NETWORK) - Several more suspects with links to the Islamic State in Iraq and Syria (ISIS) have been picked up, said Malaysia's Inspector-General of Police Tan Sri Khalid Abu Bakar on Thursday (July 7).

Khalid confirmed the arrests when he spoke to The Star at the Hari Raya open house of Attorney-General Tan Sri Mohamed Apandi Ali .

He added that a manhunt was still ongoing for two suspects of last week's grenade attack at a nightspot in Puchong, Selangor, located about 20km from Kuala Lumpur.

Eight people were injured in the attack when a grenade was lobbed at patrons of the Movida nightclub. The police previously confirmed that the grenade blast was the first successful ISIS attack in Malaysia.

"They have gone into hiding but we are confident that we can track them down," said Khalid.

A nationwide manhunt has been launched to track down 28-year-old Md Saifuddin Muji and 33-year-old Jasanizam Rosni, who are high on the police wanted list for their involvement in the grenade attack.

He added that police were also keeping a close watch on social media websites and deploying more personnel to sensitive areas, and reminded the media to not publicise the activities of militants or their new threats.

"Let's not give them space and the avenue to project themselves. We are aware that several of them are aiming to be the local cell leader by planning more dastardly acts," added Khalid.

It is learned that three Malaysians were vying to lead the local ISIS cell. They were Mohd Rafi Udin, alias Abu Awn Al-Malizi from Negri Sembilan, Muhamad Wanndy Mohamad Jedi alias Abu Hamzah Al-Fateh from Malacca and Zainuri Kamaruddin alias Abu Thalma Malizi from Perak.

On police personnel being influenced by ISIS, Khalid said that no more personnel were found to have been influenced aside from the two already detained for questioning.

Meanwhile, Malaysia's Education Ministry is in discussions with the police with a view to conducting anti-terrorism talks in schools.

Deputy Education Minister Chong Sin Woon said this would be a start in the prevention of terrorism and halting the penetration of ISIS ideology into schools.

He added that the ministry was also working on suitable programs to be implemented in schools.
