Christian Slater's alleged sexual assault victim is pursuing legal action against the actor because he angrily ordered her not to press charges, instead of apologising.

The "True Romance" star was arrested Tuesday after he allegedly touched the 52-year-old drug counsellor's bottom while intoxicated, in Manhattan, New York, reports celebrity portal Femalefirst.

Slater was booked on two sexual misconduct charges and released from police custody. He is due to appear in court June 14.

But the unnamed woman refused to drop the charges because she was disgusted by Slater's attitude after the assault.

She told Fox TV: "He didn't even say sorry. Instead, he said 'Drop it'."
