On 28 February 1838, nine days after the attack on Miss Alsop, 18-year-old Lucy Scales and her sister were returning home after visiting their brother, a butcher who lived in a respectable part of Limehouse. Miss Scales stated in her deposition to the police that as she and her sister were passing along Green Dragon Alley, they observed a person standing in an angle of the passage. She was walking in front of her sister at the time, and just as she came up to the person, who was wearing a large cloak, he spurted "a quantity of blue flame" in her face, which deprived her of her sight, and so alarmed her, that she instantly dropped to the ground, and was seized with violent fits which continued for several hours.
