Insp Herman Lee


Central Narcotics Bureau


Senior Executive, Research & Planning

Job Description:

Insp Herman Lee’s appointment requires him to study and analyse the drug situation to put forth recommendations to deal with the current and emerging trends. The work includes analysis of abuser profile, understanding and predicting drug trends and participation in both inter-departmental and ministry meetings.

His earlier ground postings leading a team of officers have given him a good understanding of CNB’s operations and realities. It has thus aided him significantly understanding the wider range of issues that affect Singapore’s drug policies.

Insp Herman, do you find your job meaningful? Why?

The work that CNB does is very meaningful and important to Singapore. It helps to ensure that our society is free from the scourge of drugs and its related harms. Apart from that, CNB also educates Singaporeans of the harm of drugs through its preventive drug and inhalant education.

In my current appointment, I am able to see the impact of how our enforcement and preventive education efforts complement each other in the fight against drugs.

My engagement with other government agencies and community partners have also impressed upon me that solutions are not one dimensional but requires coordinated and multi-faceted approaches. The need to always review and relook our anti-drug policies and understand the changing drug situation ensures that work is always challenging.

Can you describe your day-to-day work?

My day-to-day work requires me to study and analyse the drug situation in Singapore. This includes understanding how our current drug policies have improved the drug situation, kept it under control and how it could be further improved to ensure that the situation remains that way. I would put up reports based on analysis of drug trends and how it affects the different communities by collating responses from surveys and inputs from ground officers during their course of investigation.

Another part of my work is to assist in the staffing of meetings. These meetings would include those internal, inter-departmental and those involving external agencies.

How do you find the current drug situation in Singapore?

The current drug situation in Singapore has been on a general declining trend since the 2000 and has been stable for the past 4 years. This has been due to the combined effort of CNB and our close working partners like Singapore Prisons Service and voluntary welfare organisations. However, we are always continuing to look for new technology and ways of enhancing our outreach to bring the organisation to the next level.

How have your earlier postings aided you in your work?

My earlier posting in an operational division has provided me with a good foundation with regard to the core functions of the bureau. It gave me the opportunity to lead officers in operations and understand the constraints faced at the ground level. It also provided me exposure to the preventive education aspect of the bureau’s work as we also participated in activities to bring across the anti drug message.

Apart from operational work, the bureau also gave me opportunities to broaden my skills in staffing work by participating and subsequently leading projects to further the bureau’s vision of a drug free Singapore.

Is there any special experience or knowledge particularly important to this job?

There is no special experience or knowledge needed to perform well as a CNB officer. However, it is important to have the passion to uphold the law as the operating environment is becoming increasingly challenging and would require patience and determination to continue to excel in it.


Insp Chee Tuck Seng Central Narcotics Bureau OC Intel Ops

Job Description: Insp Chee’s appointment requires him to lead Narcotics Officers in a range of challenging assignments including undercover work, gathering intelligence on drug syndicates and executing field operations against drug offenders. Other than that, he conducts meticulous investigations and surveillance operations to neutralise drug trafficking groups. Formulating, implement or review drug enforcement policies and strategies is also part of Insp Chee’s responsibilities.

What are your job scope and responsibilities?

1. To assist in the collection plan and collation plan of Intelligence Division on target areas or subjects of interest in drug activities.

4. To advise on coordination and requirements of intelligence collection plans by CNB Intelligence Division.

What qualities should an Intel Ops officer possess?

An Intel Ops Officer should possess good analytical skills as he/she need to pore through tons of data to sieve out possible targets. Perseverance through investigation is important too as drugs targets might be elusive and we need to monitor for a prolonged period before the case can be concluded. Excellent interpersonal skills is one of the assests as a Intel officer needs to work extensively with people.

Are there any risks associated with this job?

Some degree of risk is involved as Intel Ops officers do execute arrest in some situation.

At the end of the day, what makes your job worth doing?

The feeking of knowing that you had stopped a large consignment of drugs from flowing into the streets with satisfaction of outwitting traffickers even when they tried their best to hide their trail makes my job exceptionally rewarding.

What advice would you give to someone who wants to become a drug enforcement officer?

One must be passionate in their job, knowing that the rewards reaped would not be in monetary terms but in the satisfaction that you had kept Singapore streets drug-free.


SSgt Desmond Chor Guo Hui Central Narcotics Bureau Team Leader, Woodlands Team

What personal qualities would make a person well suited for this job?

What are the risks associated with this job?

Some drug offenders may turn very violent during arrest as they know that they would be facing capital charges that lead to the mandatory death sentence. However all officers are put through a basic training of 28 weeks which will equip them with necessary skills to protect themselves.

What areas did you find difficult and challenging in your line of work?

Firstly, to deal with un-cooperative passengers professionally could be a challenge. Secondly, we have to be constantly keeing up-to-date with the new concealment methods that are used by drug traffickers and drug smugglers.

CNB Management recognises the effort that every officer puts into their jobs. For Narcotics Officers who perform well and possess the potential, there are many career development opportunities such as promotion to the senior ranks.

Besides rigourous drug law enforcement, CNB actively reaches out to students and youths to equip them with the knowledge needed to stay clear from drug activities and help stamp them out.
