"We will decide Wednesday when to summon former president Park and inform her," the spokesman of the Seoul Central District Prosecutors Office told AFP.
"She will be summoned as a suspect," he added.
It has not yet been decided whether Park will be called in to the prosecutors' office in private, or publicly before TV cameras and photographers, he added.
The country's top court last week fired Park over a corruption scandal, stripping her of her presidential immunity from criminal prosecution.
