The Immigration Department has acted against 37 officers for sabotaging the Malaysian Immigration System (myIMMs), sacking 15 of them, suspending 14 and freezing the salary movement of eight, said director-general Datuk Seri Sakib Kusmi.

He said the penalties were meted out since February to these 37 officers who included those working at major entry points into the country, information technology staff and officers working with the vendor of the system.

"Some of them had joined the department just six months earlier while others had worked for up to 15 years," he told a press conference at the KL International Airport here today.

Asked whether the officers would be prosecuted for misuse of authority, he said that would depend on the investigation conducted by the police.

Sakib said about 20 more officers suspected to have been involved in the sabotage were under observation and subjected to an internal investigation by the department.
