Between 30th November and 3rd December, opinion was divided among the medical men gathered there. Mary produced no more new rabbits, but continued to appear to go into labour. She was also badly infected and had fits which made her lose consciousness. Shortly thereafter, a porter at Mr. Lacy's bagnio was caught trying to sneak a rabbit into Mary Toft's room. He confessed to Douglas and Manningham that Margaret Toft (Mary's sister-in-law) had asked him to procure the smallest rabbit he could find. Manningham and Douglas were determined to obtain a confession of guilt from Mary but decided to see if she would incriminate herself. They didn't have long to wait as she went into labour on 4th December but produced nothing. On that evening they called Sir Thomas Clarges, Justice of the Peace, to the bagnio. The porter, Thomas Howard, swore a deposition before him and Clarges immediately took Mary into custody for questioning but she would admit nothing. Over the next two days, much pressure was put upon her to confess but Mary held out until Sir Richard Manningham threatened to perform painful experimental surgery on her to see if she was formed differently from other women. Toft was forced to admit on 7th December 1726 that she had manually inserted dead rabbits into her vagina and then allowed them to be removed as if she were giving birth. In several different confessions, she implicated a mysterious stranger, the wife of the organ grinder, her mother in law, and John Howard. On the 9th December, Mary Toft was charged with being a "Notorious and Vile Cheat" and sent to Bridewell prison where, allegedly, she was exhibited to large, curious crowds by her warders.
