Malaysia’s airport security has come under scrutiny following last month’s arrest of an airport security guard for suspected links to Islamic State (IS).

He is believed to be the second airport personnel to be arrested by the Royal Malaysian Police in the past two years, a development counter-terrorism police and experts called a concern.

While initial investigations showed he was not planning any terror attack, he had plans to go to Syria to join IS, according to police.

… Counter-terrorism expert Associate Professor Kumar Ramakrishna, who heads policy at the S. Rajaratnam School of International Studies, called the incident a “classic case of an insider threat” where airport security may be compromised by radicalised “insiders working within the system”.
