Alexandria had long been known for it's violent and volatile politics. Christians, Jews and Pagans all lived together in the city. One ancient writer claimed that there was no people who loved a fight more than those of Alexandria. Immediately after the death of Hierax a group of Jews who had helped instigate his killing lured more Christians into the street at night by proclaiming that the Church was on fire. When the Christians rushed out the largely Jewish mob slew many of them. After this there was mass havoc as Christians retaliated against both the Jews and the Pagans - one of which was Hypatia. The story varies slightly depending upon who tells it but she was taken by the Christians, dragged through the streets and murdered.
…it doesn’t make sense that Hypatia was dragged through the streets by the Christians since they were the ones the Jews were after.
