"Four individual suspects involved in a terrorist group were caught," Tan Sri Khalid Abu Bakar said in a statement.
He clarified that three of those detained have been held in southeastern Turkey since November. They were sent back to Malaysia and arrested on January 11.
The fourth suspect was apprehended after a four-day counterterror operation.
"Suspect claims to have been ordered to launch a suicide attack in Malaysia after taking orders from foreign citizens, Islamic State members in Syria," Bakr added. "The suspect is a person responsible for hanging the Islamic State flag in several locations."
Bakr named Malaysian citizen Muhammad Bin Mohamed Jedi as a person who recruited three Malaysians caught attempting to cross into Syria to purportedly join Daesh in November.
Daesh is banned in a number of countries including Russia and the United States.
