Cape Town - A man was arrested on Thursday following the murder of a Cape Town traffic officer, Western Cape police said.

Steenberg police caught the 26-year-old, from Parkwood Estate, and confiscated two firearms, Captain FC van Wyk said.

One of the guns belonged to traffic officer Wesley Woodman, 35.

Woodman and a motorist were shot dead on Prince George Drive, in the Lavender Hill area, around 9am on Wednesday.

City of Cape Town safety and security mayoral committee member JP Smith said on Wednesday the officer had stopped a Toyota Corolla for a broken tail light, when the killer approached him from behind and opened fire.

The motorist, Shuaib Afradien, died on the scene. Woodman died in hospital later that day.

The arrested man was expected to appear in the Wynberg Magistrate's Court on a double murder charge on Friday. - Sapa
