A 65-year-old man was arrested for allegedly raping and impregnating a 14-year-old girl at Ngunjaneni reserve near Mthubathuba, KwaZulu-Natal police said on Monday.

"It is alleged that the victim's mother was told by one of her neighbours that she must check her daughter as she was suspected to be pregnant," said Captain Thulani Zwane.

"The victim was then called in and checked and was found to be five to six months pregnant. When questioned, she told her parents that she was allegedly impregnated by a 65-year-old neighbour."

She said the neighbour told her not to tell anyone about the rape.

"The matter was reported to the police and the suspect was then arrested and detained in Kwamsane police cells."
