Two immigrants from Ghana were riding the bus, the 101, which passes every ten minutes. Two local guys got on the bus, smoking cigarettes, which is not allowed. The immigrants asked the Palermo boys to put out their cigarettes, and the two started to beat up the immigrants, who defended themselves. The bus driver stopped the bus in Via Liberta and a passenger called the police. One Ghanaian ran off but his companion and both Palermitani guys were arrested by police for fighting. Doesn't seem fair.
