Apollocrates in Wikipedia

Apollocrates was the son of Dionysius II of Syracuse. Two years after Dion and Heraclides conquered Syracuse in 357 BC, Dion maintained control of the fortress of Ortygia. As supplies ran out, Apollocrates capitulated to Dion, who allowed him and his mother Doris to sail to join his father in Italy. According to Theopompus, Book 39, F185: "Apollocrates the son of the tyrant Dionysius was undisciplined and an alcoholic."
