It would be "very useful" for the law to introduce heavier penalties against those who abuse private security officers, said Singapore's security industry associations, in the wake of an officer being assaulted at the Roxy Square carpark.

The call was made by the Security Association Singapore (SAS) and the Association of Certified Security Agencies (ACSA) as well as training provider Leacov School of Security as they pledged to look into "all ways" to ensure officers are able to keep themselves safe.
