San Francisco police have detained a woman in connection with two small arson fires set at a house that served as the backdrop to the popular "Mrs. Doubtfire" movie that starred actor Robin Williams.

Police spokesman Albie Esparza says detectives were interviewing the woman Wednesday in her home south of San Francisco. An arrest is expected.

The home from the movie is owned by a plastic surgeon that assists transgender woman. The homeowner told police the arsonist may be a disgruntled former patient. Esparza said that former patient is the woman who has been detained. Esparza said the woman's name and charges won't be released until she is formally arrested and booked into San Francisco jail.

The fires were set Monday night and caused minimal damage.
