In the last week, at least five pensioners have fallen victim to scams which left them with counterfeit money at two pay points in Pretoria.
Four pension fund beneficiaries were duped at the Kopanong centre in Akasia, while the other was taken advantage of at a facility in Ga-Rankuwa.
Sassa's Nandi Mosia says they are carrying out their own inquiry, alongside a police probe.
