A 41-year-old woman has been apprehended for reportedly stabbing her boyfriend with a pair of scissors, while another man is charged of beating his girlfriend with a stick in a weekend of domestic abuse in Johannesburg.

"It is alleged that the suspect stabbed her boyfriend once in the upper body with a pair scissors," said the police.

According to the police, the woman faces a prosecution of attack with intent to cause grievous bodily harm in nexus with an incident in their apartment on the corner of Plein and Wanderers streets in downtown Johannesburg on Sunday.

The police said the couple had an argument over airtime that had "disappeared" from the boyfriend's cellphone.

"The suspect took the phone and threw it on the floor and stabbed her boyfriend. The victim went to hospital, where he was treated and discharged," said police.

In a separate incident, police apprehended a 23-year-old man on Sunday in Selby Street, south of the Johannesburg CB, also for attack with the intention to cause grievous bodily harm.

"It is alleged that the boyfriend assaulted his girlfriend with a wooden stick. The victim confronted the suspect over why he was cheating with another woman," said the police.

When the woman told her boyfriend that she was ending the relationship, he reportedly attacked her.

Both suspects will face the Johannesburg Magistrate's Court on Monday.
