They’ve already heard from “multiple” female victims. But yesterday, a Manhattan grand jury heard accused Riverside rapist Hugues Akassy speak in his own defense for some 90 minutes.

And the sweet-talking “French journalist” still isn’t done.

“He’s not finished with his testimony,” Assistant District Attorney Jessica Troy told a Criminal Court judge of Akassy, who is being held in last month’s Riverside Park rape and other sex crimes.

She said he will be cross-examined today.

Akassy, 42, was arrested July 27 after allegedly chatting up a Russian tourist and inviting her for a picnic at Riverside Park, and then leading her to a secluded area and raping her.

A source with knowledge of the case has said “multiple” female complainants have testified against him in the grand jury.
