Singer Kesha has decided to sue her former producer Dr. Luke after accusing him of sexual assault and abuse.

Kesha's attorney Mark Geragos has said that the suit comes after a decade of mistreatment at the hands of Dr. Luke, born Lukasz Sebastian Gottwald, reports the Los Angeles Times.

"This lawsuit is a whole-hearted effort by Kesha to regain control of her music career and her personal freedom after suffering for 10 years as a victim of mental manipulation, emotional abuse and sexual assault at the hands of Dr. Luke," Geragos wrote.

"The facts presented in our lawsuit paint a picture of a man who is controlling and willing to commit horrible acts of abuse in an attempt to intimidate an impressionable, talented, young female artist into submission for his personal gain. Kesha is focussed on moving her life and her career beyond this terrible time," he added.

According to the Los Angeles Times, the allegations in the civil suit, filed in Los Angeles County Superior Court, have claims that Gottwald forced her to drink and take drugs against her will and forced himself on her sexually.

`On one occasion, Dr. Luke forced Ms. Sebert to snort an illicit drug before they were scheduled to take a flight. On the plane, Dr. Luke continuously forced himself on Ms. Sebert while she was intoxicated and drugged," Geragos said, the paper reported.

The suit claims that on another occasion, Dr. Luke instructed Ms. Sebert to take 'sober' pills.

"Ms. Sebert took the pills and woke up the following afternoon, naked in Dr. Luke's bed, sore and sick with no memory of how she got there.`
