Mystery surrounds the discovery of a badly burnt torso in Bushkoppies in southern Johannesburg.

The torso was discovered on Thursday, a day after community members found a human head and hand, sparking fears in the area.

Police said the dog unit was called in to try and establish if the head and hand were linked to the torso.

The police's Nondumiso Mpantsha said it was possible another body would be found.

Mpantsha urged people to come forward if their family members have gone missing.

She said community members with information must make use of Crime Line by smsing their anonymous tip-offs to 32211.

Bushkoppies residents have been left shaken by the gruesome find and are appealing for an increase in police patrols.
