"I think any alleged rape or sexual assault needs to be fully investigated. This is a particular issue between the member state and the US government, but we'll keep an eye on it," Dujarric said during a press briefing.
Dujarric pointed out that there has been some early misreporting on the matter and added that the person is not working directly for the United Nations, he added.
The suspect is claimed to be 46-year-old diplomat Charles Oliha who was taken into custody but was released based on having diplomatic immunity, according to reports.
The diplomat allegedly followed his victim to her apartment, despite her rejecting his advances, where he raped her twice, the reports said.
