The lead singer of a British pop trio climbed a telecommunications mast behind the main stage at a Belgian rock festival and leaped to his death in the parking lot below, police said yesterday.

Charles Haddon (22), of Ou Est Le Swimming Pool, died during the Pukkelpop festival in Hasselt, a town in eastern Belgium. Police say they are treating it as a suicide.

On Thursday, Michael Bean, frontman for US group The Call, died of an apparent heart attack at the same festival. The 60-year-old was working as the soundman for his son's band, Black Rebel Motorcycle Club.
