"He was superglued to the seat... his hands were superglued, as were his feet and then his mouth was superglued shut," a Netcare 911 spokesman said.

The man was kidnapped mid-morning in a wealthy suburb and forced by gunpoint to take the assailants to his house.

He was rescued about three hours later when his partner arrived home.

Sapa news agency reports that the attackers ransacked the house while helping themselves to their victim's whiskey.

"Chemicals were used in combination with Vaseline to crystallise and help loosen the superglue," Netcare 911's Mark Stokoe said.

Netcare 911 told the BBC News website that the victim was recovering from the shock and was not been admitted to hospital.

Every day, more than 300 murders and violent attacks take place in South Africa, making it one of the three most dangerous countries on earth.
