Disgraced former San Diego Mayor Bob Filner is now a free man.  

Filner's three-month house arrest came to an end over the weekend, but a source close to Filner says his GPS tracking device had already been removed.  

The ex-mayor says he's done a lot of soul searching serving out his sentence, working to become a healthier, more balanced person.  

Filner received his sentence of house arrest after pleading guilty to felony false imprisonment and two misdemeanor charges of battery involving victims of sexual harassment.  

He now starts serving his three years probation.
