Two days after being arrested for reportedly slapping a security guard outside the Academy Awards' Governors Ball at the Oscars, Sean Young says she's still waiting for an apology.

The 52-year-old Blade Runner actress says she has not yet received an apology from the Academy ... whom she says is at fault for the security guard incident.

Online reports claim Young was outside the Oscars bash, taking photos with fellow celebs, when security guards asked the actress to leave the party because she didn't have a ticket.

Just yesterday Young told X17online exclusively: "I was well-behaved. It was fine... and the surveillance tape will bear that out … It's atrocious behavior on the Academy's part."

When asked this morning how she's doing, Young tells us her fans have helped her get through this ordeal.
