Police have apprehended one man who is suspected to have been part of muggers who assaulted a Belgian national in her Umhlanga home earlier this week.

"He was travelling in a vehicle that was stolen from the home of the victim. He was nabbed in a roadblock in the Inchanga area," police spokesperson Captain Raymond Deokaran told News24 on Wednesday.

Deokaran said that a firearm, thought to be stolen from the victim's home, had also been recovered during the apprehension.

The woman, in her 70s, was alone at home when robbers stormed her residence over the weekend.

After family members failed get hold of her on the phone, a friend was contacted. The friend discovered her lying in the passage with a fatal wound on the head.

Now recovering in hospital, the woman said she would be able to identify her attackers.

"She indicated to the investigating officer that she would definitely recognise them," Deokaran said.

The suspect would probably face Verulam Magistrate's Court on Friday.

"We will be opposing bail because we have not located the other suspects."
