Police are investigating a report by "American Idol" judge Paula Abdul that a man assaulted her at a private party over the weekend.

On Tuesday, Abdul filed a report at the Hollywood station claiming she had been a victim of battery about 1 a.m. Sunday, police Lt. Paul Vernon said Thursday.

"According to Abdul, the man at the party argued with her, grabbed her by the arm and threw her against a wall," Vernon said. "She said she had sustained a concussion and spinal injuries."

Abdul provided police with the name of the man, but Vernon withheld it pending further investigation. The man had not been charged, Vernon said.

Abdul's publicist Michelle Bega declined to comment. The incident was first reported by Us Weekly.

Abdul, who shares judging duties on FOX's hit talent show with Simon Cowell and Randy Jackson, appeared as scheduled on this week's "American Idol."

Last week, she signed a deal to remain on the show for another three years.

"American Idol" airs on FOX, which is owned by the parent company of FOXNews.com.
