A 28-year-old man was shot dead in Brenda Street, Kalkfontein, last week.
Captain Isaac van Niekerk, of Kuils River police, said the man was walking in Brenda Street on Friday July 21, at 9.50am, when two men passed him, one pulled out a gun and shot him in the chest.
Both men fled as the wounded man stumbled into the yard of a nearby house, where he collapsed and died.
Captain Van Niekerk said the incident was not gang related.
Brackenfell police arrested a teenage girl for perjury last week. The girl, 17, had reported to police and on social media that she had been assaulted by two men in a park in Hibiscus Road, Protea Heights, at about 11am.
On Facebook the girl had posted pictures of her alleged injuries and details of the alleged attack, but police say they later found information disputing her claims.
