KUALA LUMPUR - There are currently eight active deviant groups operating throughout the county, said Datuk Seri Jamil Khir Baharom on Tuesday.
The minister in the prime minister's department said these groups were difficult to keep in check because they operated below the radar.
However, he said, they were not as aggressive as the group suspected of killing Pahang Islamic Religious Department (Jaip) enforcement chief Ahmad Rafli Abdul Malek.
Gunmen shot dead Ahmad Rafli outside his house in Indera Mahkota 2 on Sunday.
"They are like a disease, we don't know when they are going to emerge" he said after handing out uniform and shoes to needy children at Kompleks Pusat Islam, Kuala Lumpur.
He added that enforcement authorities found it difficult to prosecute members of deviant groups because of the burden of proof required and lack of witnesses.
