This Saturday night was much more boisterous than usual. Lots of young people just finished their trip to Moomba Festival, holding large plush toys and walking back to city. The streets were filled with excitement and joy. My friend and I were sitting on the bench near the entrance of Melbourne Central and chatting. At this moment, three police officers suddenly darted into the alley after two guys, and their speakers kept ringing to report the current location of suspects. Another two police was standing on the other side of the road in case of an accident. My friend told me that those two guys were thieves and they once stole sneakers when he was working in that shoe store. I thought the chaos would end up like this, shockingly, we heard another noise from State Library. A group of African Australian girls, looked like high school students, were quarrelling with a couple. A box fell on the ground, and the girl who got attacked trying to pick it up and almost started a fighting. Fortunately, the police came over to maintain order.
