A 40-year-old man will appear in court on Monday for allegedly throwing his girlfriend from the window of her fifth floor flat in Alexandra, Johannesburg police said.

"He beat her and throttled her until she lost consciousness, he then threw her out from the fifth floor window of her flat... her screams were heard until she fell to her death," said Constable Neria Malefetse on Friday.

The murder occurred in November. The man was arrested on 9 December after police investigations.

"The neighbours heard the screams and went to the flat. The man then told them that they were robbed and his girlfriend jumped out of the window while trying to escape."

He would appear in the Wynberg Magistrate's Court.
