8:15 AM PT -- Sources tell us Hilton allegedly first went to the home of E.G.'s ex husband Rick Salomon -- the father of Hunter -- and stole his Bentley. You may see a connection here ... Conrad's sister, Paris, starred in her famous sex tape with Salomon ... and Conrad ended up dating his daughter.

Conrad Hilton, Paris Hilton's little brother, has been arrested for allegedly trying to break into the home of actress E.G. Daily and violating a restraining order E.G's daughter has against him.
