French authorities are still trying to track down the armed men who staged a daring robbery on a casino near Marseilles on the weekend.

Early Saturday morning, four masked men armed with Kalashnikov automatic rifles entered the Pasino venue in Aix-en-Provence, a small city a few miles north of Marseille on France’s southern coast.

The men, who were wearing balaclavas, fired several warning shots into the ceiling. Coming so soon after November’s Islamic terror attacks in Paris, the crowd of around 700 inside the casino panicked and stampeded for the exits.

One of those present at the time told France 2 television that many of the panicked guests were “trampling over those who had fallen over, it was the behavior of animals.”
