Firefighters from Bracknell and Crowthorne were called to an address in Pond Moor Road at about 8.30pm last night to reports of a shirt being set alight.
They arrived to find the fire had been put out by an extinguisher and the woman who had apparently started the fire had fled the scene.
Police later found the woman and took her into custody.
A police spokesperson said: "A woman has been detained under the mental health act and as such, it would inappropriate for us to comment any further."
