(CNN) A United Nations whistleblower who accused a high-ranking official of sexually assaulting her has been fired over alleged financial and sexual misconduct.

She says that it was retaliation for her own complaint of sexual assault. The investigation that would lead to her dismissal was started by her alleged assailant.

Martina Brostrom, who first went public with her allegations against an assistant secretary general at the UN in a CNN interview in March 2018, says that she was dismissed from the organization on Friday. She denied charges of misconduct linked to her dismissal.

"This is what the UN does to women who report their sexual offenders," Brostrom, a policy advisor at UNAIDS, the United Nations' global AIDS program, told CNN. "[They] just want to get me out of the organization."

Reached for comment, UNAIDS did not confirm the firing of Brostrom but told CNN that "two staff members were dismissed from UNAIDS after an independent investigation proved beyond reasonable doubt, that they had misused UNAIDS corporate funds and resources and had engaged in other misconduct, including sexual misconduct."
