Actress Sean Young was arrested Sunday night on suspicion of misdemeanor battery after an alleged altercation with a security guard at an Oscars after-party.
The 52-year-old Blade Runner star was placed under a citizen's arrest at the Governor's Ball, the official post-Oscar party held near the Academy Awards show venue in Hollywood.
A police report obtained by ET shows that Young was booked at the Hollywood police station, where she posted $20,000 bail and was released at 2:55 a.m. on Monday.
In addition to Blade Runner, Young is known for other acting performances throughout the '80s including Dune, Stripes and No Way Out. She also appeared alongside Jim Carrey in the 1994 movie Ace Ventura: Pet Detective.
