There are strict rules against high-rise littering in HDB buildings, but little seems to be done to punish incorrigible litterbugs in private condominiums.

In the last two months, my family has had to put up with lighted cigarette butts and ash being thrown by a new tenant who moved into the unit above ours.

We have reported the matter to the National Environment Agency (NEA) and the condo management on several occasions, but no action has been taken against the culprit even when he was caught red-handed by us (as witnessed by the condo's security officers).

The NEA claims that condos do not come under its purview and that the matter should be handled by the condo management.

But the condo management is toothless, as it is not able to impose fines or corrective work orders like the NEA can.

Knowing that NEA will not act, the tenant continues to litter.

Is there no way the authorities can step in?
