The body of a young girl was found on Muizenberg beach on Friday, Cape Town police said.

The girl had been buried in the sand.

"Because the body of the girl was exposed to the elements, it is not possible to make an identification yet, or to speculate on her age," Lieutenant-Colonel André Traut said.

The cause of her death would be established during a post-mortem, he said.

"Forensic procedures will be used to determine her identity."

Police are investigating a case of murder.
