Photograph, surveillance image

Surveillance image mounted on card of a Suffragette prisoner exercising in the yard of Holloway jail, taken by an undercover police photographer. Handwritten on the back is ‘Lillian Ball’.
Lillian Ball and Marguerite Sidley were arrested on 11 February 1914 and detained for four days in Holloway Prison. Surveillance photographs of the women, including this one, were taken during this period. Lillian & Marguerite were members of the Women's Freedom League. They were arrested while delivering a speech from the steps of the Board of Trade Offices in Whitehall.

Scotland Yard undertook covert photography of militant suffragettes from 1913. The images were used to identify suffragettes attempting to enter public buildings such as museums and art galleries, where they might attempt to damage the objects.
