Authorities are looking into allegations that Nicolas Cage abused his five-year-old son the same night he was arrested for arguing with his wife.  Police in New Orleans say a witness told them he saw Cage pull his young son to the ground on the night of April 15th.  Cage's wife, Alice Kim, told police she was arguing with her "intoxicated" husband when they returned home from picking up their son at his friend's house.  Kim claims that Cage fell while holding their son, but the witness says he saw the "Drive Angry" star pull his child to the ground by his hand.  According to, a child abuse detective was notified, although Alice won't let police speak with her son.
