The name Caligula is actually only a nickname, picked up during his childhood.
The statue, made of rare Greek marble, is of a god (Caligula proclaimed himself a living god) sitting on a throne and wearing Roman caligae (sandal boots). One thing led to another and now the archaeological squad of the police believe the area to be the burial site of Caligula. Commanded to do so, the man led police back to where he'd found the monument. According to recent reports, a man was caught and arrested as he attempted to load a statue into his truck around Lake Nemi, just south of Rome.
