Police arrested six people, including a medical laboratory student for suspected involvement in the Islamic State (IS) militant group.
The police’s counter terrorism unit conducted an operation between March 24 and April 25 in Kelantan, Malacca, Johor, Selangor and Penang which led to the arrests.
Of the six, two were women.
In a statement, the Inspector-General of Police Khalid Abu Bakar said two men aged between 26 and 41 arrested in Kelantan on March 24 and 25.
The two were suspected of conspiring in weapon smuggling activities from Southern Thailand to be used by IS members in Malaysia.
The following arrest was made on April 4 at the Kuala Lumpur International Airport (KLIA) in Sepang on a 26-year-old woman, who was a medical laboratory student at a public college in the Klang Valley.
She was said to have left for Turkey last year to join the IS militant group in Syria. However in February this year, she was detained by Turkish authorities while waiting for instructions from Malaysian militant Muhammad Wanndy Mohamed Jedi to enter Syria.
Two other suspects, a male and a female were nabbed in Malacca and Johor.
Another male suspect who was said to have been actively promoting IS activities on Facebook since 2014 was detained in Penang on April 25.
“The suspect was planning on launching an attack at a Syiah Mosque around Penang,” the IGP said.
Meanwhile police are looking for a suspect believed to be involved in gun smuggling activities from Southern Thailand.
Police believe the suspect, Muhamad Muzaffa Arieff Junaidi, 27, is from the same terror cell as the first two suspects detained in Kelantan.
Those with information on his whereabouts are urged to call investigating officer Inspector Mohd Badri Othman at 011-26924829.
