Fights broke out in French supermarkets after they started selling the hazelnut-and-cocoa spread Nutella at a steep discount, according to local media.

The sales at the Intermarché chain—€1.41 ($1.76) a jar, representing 70% off—prompted “riot scenes everywhere,” according to the Lyon-based newspaper Le Progrès .

The paper reported that people “threw themselves” on store employees who were bringing out pallets of the popular spread.

“They are like animals,” reported one customer, who talked about bloody hands, pulled hair and people being punched in the head.

Founder Pietro Ferrero hit upon the idea of using hazelnut—abundant in his native Piedmont region—in order to save on expensive chocolate when making confectionary.
