City Attorney Jan Goldmith said Friday that Mayor Bob Filner is back a week earlier than expected from therapy triggered by sexual harassment allegations and that the locks to his office have been changed. The mayor's surprising return comes after he reportedly checked into a counseling clinic a week earlier than his announced Aug. 5 start of what he said would be two weeks of intensive therapy to address concerns about his interaction with women. It was not immediately clear who ordered the locks to the mayor's office changed or why.
