Shock rockers Slipknot have been accused of influencing a string of attacks - including a murder - at a South African high school.

A schoolboy, reportedly dressed as the band's drummer Joey Jordison, stabbed a fellow pupil to death with a sword and then attacked and wounded two gardeners at Nic Diederichs Technical High School in Krugersdorp on Monday morning. Fellow students tell cops the unnamed boy was mimicking the rocker's appearance, and that he had claimed Satan instructed him to carry out the attacks.

Jacob Raboroko, from Johannesburg police, tells News24.com, "He stabbed one of the school kids in the neck and he died. He then went further and stabbed a gardener in the back and another gardener in the face. They were taken to hospital in serious conditions."

It's not the first time the band has been accused of influencing criminal acts. In 2003 two young killers claimed lyrics from the band's song Disasterpice drove them to murder, and last year words from the track Surfacing were found at the site of a grave robbing.
