Johannesburg - ANC Western Cape chairperson Marius Fransman has spoken out following a sexual harassment complaint that has been laid against him in the North West on Friday.Posting on his Facebook account, he wrote: "Hi couldn't post anything last few hours as I just had to deal with all the calls from the comrades that are concerned."Those of you that know me will know if I did such an act or not."Fransman also denied reports that he had been arrested.He said it was the right of any South African to lodge a complaint against another person, but this did not necessarily mean the complaint was true."I am deeply appreciative of everyone that already gave messages of support even if I understand that it's possible to doubt. Also to those leadership in all other political parties that either called or send message [sic].""I am bringing a statement out but lets continue to celebrate the 104years!," he said.Earlier, the ANC confirmed that the complaint had been laid against Fransman."We have been in touch with Marius to get an explanation. Of course the law must take its course," party spokesperson Zizi Kodwa said.North West police spokesperson Sebata Mokgwabone told News24 on Friday afternoon that a case was opened and was under investigation. No one has yet been arrested. "A case has been opened and it's under investigation. I can't divulge what the case is, we will allow the investigations to continue and only once they are concluded can we determine if a person will be charged."Kodwa said police should be allowed to investigate the matter."We must reaffirm our position as the ANC in terms of respect to women. It is important to always reaffirm that position without prejudice of what happened but as a point of reference."He said Fransman had explained to the ANC what had happened, but the party was aware that this was only one side."It's a matter under investigation. It's one side. In any case it may be important to allow police [to investigate] so that we don't prejudice the complainant in the case," Kodwa said.The ANC in the Western Cape said it would meet on Saturday to discuss the allegations made against Fransman. Spokesperson Yonela Diko said the party did not have any details about the incident for now.
