According to the Des Moines Register, Slipknot and Stone Sour frontman Corey Taylor's home was robbed of more than $36,000 worth of musical equipment.

The perpetrator behind the robbery is alleged to be a "friend" of the singer, and the theft took place while Taylor and his wife were on tour in Europe.

Among the equipment stolen were two bass guitars once owned by former Slipknot bassist Paul Gray, who died in 2010.

The police report reveals that Taylor's wife was told by a friend that the suspect had been stealing musical equipment from the couple's home and storage units.

Another friend became suspicious when he heard the suspect asking to buy equipment back from a local guitar store.

Some of the stolen equipment has since been located at the guitar store, and the store's manager is working to retrieve equipment that was already sold.
