Cause of the violence in the Moroccan city of Casablanca is unknown

Cause of the violence in the Moroccan city of Casablanca is unknown More than 190 football fans were arrested in Morocco on Friday for their alleged involvement in acts of violence before and after Thursday’s 1-1 draw between Raja Casablanca and FAR de Rabat in matchday 23 of the Botola league, the interior ministry said.
Authorities said supporters entering or leaving the Casablanca stadium damaged public and private property including shops, vehicles and also caused public disorder in the city.
The newly constructed tramway line was also tampered with as well as public transport buses, the statement added.
It is still unclear what caused the uproar, though local pundits suggest rivalry between fans of the two sides could be the cause.
A police report earlier said investigations had been opened while the hunt for more suspects continued in the country’s largest city.
