Mystery surrounds the origin of a damning document, leaked to the media, which seeks to divide the ANC Youth League in Limpopo ahead of the ANC's provincial congress.
The document says youth league chairman Lehlogonolo Masoga does not approve of Cassel Mathale becoming ANC chairman.
Mathale, current provincial secretary of the ANC, is being lobbied to become chairman.
The e-mailed document, clearly sent from Masoga's personal e-mail address, contradicts the ANCYL's stance that Mathale should become chairman.
The dossier also insinuates that Masoga believes Mathale has shortcomings but he could not state this in case the document was leaked.
"I actually do not think Mathale is the right person to take our province forward - to where we should go," the dossier says.
Masoga yesterday denied knowledge of the document. He said he had opened a case with the police.
Masoga claimed the document came from desperate people "who are afraid of change".
Polokwane police spokesman Captain Mohlaka Mashiane said they were investigating a case of fraud.
