…was destroyed as the result of a street battle between Christians and pagans… “As the result of…” is a clever rhetorical trick. It makes it sound like a frenzied mob swarmed the Serapeum and wrecked it. In fact, it was demolished by imperial decree as part of an amnesty deal for the pagan rioters who had holed up there and sacrificed their Christian prisoners on the altars. The Serapeum on the acropolis was a traditional refuge for Alexandrian rioters of every stripe, difficult for even the military to attack. So “as a result of” the rioting is technically correct, but misleading.
