The singer was convicted of assault earlier this month after attacking Danielle Dodoo and threatening to bite off her nose.
The incident happened in the VIP area of Alto, a club owned by Berrabah's boyfriend Tom Benn in London's Soho. Berrabah denied common assault but was found guilty at the City of Westminster Magistrates' Court and ordered to pay £250 compensation.
"Amelle may have apologised to the band, her fans and her management but she hasn't once said sorry to me," Dodoo told the Daily Star Sunday. "How can she be a good role model for young girls? It's disgusting. All I did was ask her politely to stop barging into me, when she launched herself at me.
"She came right up into my face and said she was going to bite my nose off. It was all very menacing. I saw her hand coming towards me and then it was around my neck. I didn't know what she was doing until I felt the pain. She'd closed her fingers on my neck. She'd clawed me."
Dodoo complained to a bouncer and waited two hours for the club's management to assist her with the complaint. When a friend came to check on her and told her who owned the club, she decided to go home and call the police.
She insisted that she was sober in the club and "felt a little out of place as I was about ten years older than the people we were meeting up with".
Dodoo added that Berrabah being drunk was "no excuse" for what happened and branded reports she was only after revenge "terribly upsetting".
"She's not sorry for what she's done," she concluded. "If she was, she'd have made a public apology to me. The bottom line is that I don't believe Amelle deserves to be in a group like the Sugababes after she's been convicted of a crime."
Berrabah was caught drink driving just hours after the attack in September last year.
