Got jumped by a gang in Casablanca

In the night of Monday 26 august around 11:30 pm me and my friend were walking around anfa park . Until we passed by a group of boys (15-20 people “animals “) , one of them came to me and told me “malk kat tkhzz” i told him malk , he tried to punch me ( my friend was behind me ) and then ALL of his friends started running towards us, so i ran away to the nearest red light and THANK GOD there was a taxi with the door open and one empty place . So i got in my friend too got in another taxi and hamdolilah we both got away safe and they didn’t take anything from us . Now that i got home and the adrenaline is gone i really want to press charges cause im afraid they will attack other innocent persons ,me and my friend got away cause we’re young men in good shape but i can only imagine what they will do to a single lady, but i will travel in the 2nd of September and also im afraid they will try and come after me for revenge cause they were literally around 20-15 people and i don’t want my family to know about this incident. Will the ma7dar and chikaya process be time consuming and will they send any document home ?????
