Bloc Party frontman Kele Okereke suffered facial bruising and a split lip following an alleged racist attack by Sex Pistols singer John Lydon at Barcelona's Summercase festival on Saturday.

Okereke, claims the attack took place after he attempted to engage Lydon in conversation backstage however Lydon became "intimidating and aggressive while his entourage responded with a racist tirade, including the statement, 'your problem is your black attitude'." Three members of Lydon's staff then allegedly attacked Okereke.

Several other musicians witnessed the fight including Kaiser Chiefs frontman Ricky Wilson who was said to have intervened in the brawl. Spanish and UK police are now thought to be investigating the incident.

Lydon made the headlines last month for his verbal attack on Welsh pop startlet Duffy at London's prestigious Mojo Awards. He is also being sued by a female assistant who he allegedly punched in the face during a frenzied argument over accommodation at a five-star Los Angeles hotel.
