How was she treated in prison, and how did it end

Elizabeth Choy had been treated brutally during her detainment days. She was subjected to beating by the Japanese officers and was even electrocuted in front of her husband. 

According to her, they dragged her husband from husband from Outram prison, tied him up and in his full view, stripped her of her clothes and applied electrical currents to her body. The electric shock sent her whole body into spasms, her tears and mucus flowed uncontrollably. 

The Japanese tried to force her into giving out the names of informants and make her admit that she was anti-Japanese. After 193 days of her imprisonment, they finally released her, learning that they would never get what they wanted from her.
