Amelle Berrabah , 23, who was arrested after a fight in a bar claimed: "I'm the innocent party."
According to the Mirror, Amelle told friends she was "devastated" over the brawl with a gang of 12 girls and guys.
Amelle was with her sister Laila, 24 when the fight broke out.
The singer who is now in the US with her fellow Sugababes - Keisha and Heidi - said, "The other girls should be the ones punished, not me. What happened was unbelievable and my sister got hit by one of the boys."
Amelle was arrested as she ripped out a girl's hair extensions. She spent a night in the cells. Police said they were looking at CCTV and "continuing enquiries".
