Sense vt 1c, in which the direct object is the thing stolen, is sometimes considered to be wrong, or perhaps archaic. The sense has been in use since the 13th century and is found in earlier literature <contrive to rob the honey and subvert the hive — John Dryden>. It is still in use though not as common as other senses <then robbed $100 after the clerk fled — Springfield (Massachusetts) Morning Union>.
