What started as an investigation on a case of public disturbance led Ms Tin Pei Ling to another find - soiled sanitary pads lying on the floor.
After the Chinese evening daily Lianhe Wanbao had reported about Ms Tin's misadventure with the high-rise litter, the MP for Marine Parade GRC sought to clarify what really transpired, and her approach towards such inconsiderate behaviour.
In a post on her Facebook page, Ms Tin related: "First, it was a confluence of events that led me to "discover" the pad. I certainly was not on stakeout!"
Ms Tin had rushed to Blk 31 Balam road off MacPherson after learning that two juveniles had attacked an elderly man.
After assessing the situation, Ms Tin was distracted by a soiled sanitary pad lying at the foot of the block.
Explaining that the structure of that particular block led her to conclude that the litterbug resided in one of the seven units above, Ms Tin decided to investigate further as the pad was relatively "fresh".
Ms Tin noted that this was not the first occurrence.
"The visit was in part to determine who the culprit was, but it was also to send a signal that we take such high-rise littering seriously," Ms Tin explained in her Facebook post.
She added: "The way I see it: if I as the MP of the area see this and turn a blind eye, then how can I expect the various groups of people tackling the littering challenge - NEA, town council and local grassroots volunteers - to work hard on this. Those who have confronted people who litter will know that it is unpleasant. "
While she described the task as 'not a "glamorous" part of the job [as a MP]', Ms Tin said that "it is not a bad idea to gain first-hand experience" periodically, noting that it would be unrealistic for MPs micro-manage.
Ms Tin later explained the community initiatives to sustain a clean and green environment, and a civilised society, but stressed on the need for action when words fail.
