The African envoy accused of raping a neighbor in their Upper Manhattan building and then dodging charges thanks to diplomatic immunity may have fled the US. No sounds came from inside Charles Dickens Imene Oliha’s apartment Tuesday when The Post repeatedly knocked, and there was no light visible from behind a red curtain fluttering in a window. The State Department wouldn’t say if Oliha, 46, left the country or if the US government was seeking to have his immunity revoked, with a rep saying, “We do not comment on the specifics of ongoing investigations. “We are aware of the incident referenced involving a diplomat accredited to the United Nations,” the representative said in an e-mail.

A representative of the Permanent Mission of the Republic of South Sudan to the UN did not return a request for comment from The Post on Tuesday.
