British rockers Cradle of Filth were forced to cut short a festival appearance in Derbyshire, England on Saturday after guitarist Paul Allender was injured by an object thrown on stage by an audience member.

The band were midway through their set at the Bloodstock Open Air festival when someone in the crowd threw an unidentified object on to the stage, striking Allender.

The guitarist needed medical attention and the group terminated their show as a result.

And the cancellation has angered organizers of the event, who have branded the attacker "selfish".

A statement from Bloodstock Open Air festival officials says, "That one selfish ticketholder soured an amazing day and a stunning performance by the closing headliners. (We hope) that the rest of the fans in attendance will enjoy the rest of the weekend with the camaraderie and unity that has made Bloodstock Open Air the great festival it is."
