Inspector Sabatha Modupe said the three envelopes laced with powder and
a note written “Remember, Remember November 5” were found by an
employee at 08.20 on Wednesday morning.

The Sars health and safety manager was called in after 18 employees and
15 clients had inhaled the unidentified substance, said Modupe.

He said workers and clients were evacuated from the building and rushed to hospital.

“The affected were treated for shock; we have not received reports of
anyone who has fallen ill after inhaling the powder,” he said
