Bogus contractors have been targeting elderly people in public housing estates, telling residents that they have been appointed by the HDB to carry out repair works.
The "required works" include replacing doors, rubbish chute covers or sewage pipes, installing security systems and repairing spalling concrete or leaking ceilings.
The HDB said residents will be given prior notice if works need to be carried out in the flats. Genuine officers are also issued with a staff card bearing their photo. Residents are advised to request identification documents for verification.
If in doubt, call the HDB branch service line on 1800-225-5432 to verify a contractor's visit.
