Los Angeles ( CNN ) -- San Diego Mayor Bob Filner , facing a growing tide of sexual harassment allegations , has completed his two-week intensive behavior therapy a week early and will begin outpatient treatment , his lawyer said . But he might not be back at work in his office any time soon . His chief of staff changed the locks , according to numerous reports , including one by CNN affiliate KFMB . Attorney James Payne said in a statement that Filner began treatment on July 29 , a week before the mayor previously told reporters he would start . Filner was to complete that phase of treatment Saturday , Payne said . Did mayor target victims of military sexual assault ? In the same statement , Payne said Filner would take some personal time this week and would not be available for comment . It is unclear when Filner will return to work , but he is believed to be back in the city he governs after his rehab stint . Victims start talking . An increasing number of women are saying that Filner inappropriately touched them , prompting his chief of staff to resign and fellow Democrats to call for him to step down . In a personal letter to the mayor Friday , Democratic Sen. Barbara Boxer , who addresses Filner as `` Bob , '' wrote : `` We 've known each other for a long time . ... So I am speaking to you now on a personal and professional level , and asking you to step down as mayor and get the help you need as a private citizen . '' California 's other senator , Democrat Dianne Feinstein , has also asked Filner to resign . Eleven women have now accused Filner , 70 , of sexual harassment while he was mayor or a congressman . The latest is nurse Michelle Tyler , who said Tuesday that Filner rubbed her arm in his office and asked for dinner dates in June in exchange for his helping a brain-injured Iraq war veteran . She said Filner told her he wanted to kiss her . While Filner acknowledged last month that `` I need help '' and said `` I 'm clearly doing something wrong , '' he has also said he believes he will be vindicated when all the facts come out . The mayor has vowed not to resign . The idea that Filner has now completed rehab and could come back to lead San Diego did not sit well with many of his constituents . `` It 's ridiculous , '' said Gary Sehnert , a San Diego resident . `` Why is this continuing ? '' `` Really mayor ? You did what you did and now you want to stay as mayor , '' said William Sawaya , another San Diego resident . `` ( Expletive ) , you 're not staying as mayor . '' Filner served 10 terms , or 20 years , in Congress before being elected mayor of San Diego last year . CNN 's Kyung Lah reported from Los Angeles . Melissa Gray reported and wrote in Atlanta .
