This about brings up to the time of its being mentioned by the Lord Mayor, the consequence of which was that a Committee was formed at the Mansion House for the purpose of receiving subscriptions and deciding upon the best means of capturing this erratic genius. Probably feeling that he had sufficiently terrorised the districts before mentioned, he turned his attention to the East end of London, and particularly favoured Bow. A case is given in the _Times_ of 23 Feb. A gentleman named Alsop, living between Bow and Old Ford, appeared before the police magistrate at Lambeth Street (then the Thames Police Office) accompanied by his three daughters, one of whom stated that at about a quarter to nine o’clock on the evening of the 21st February, 1838, she heard a violent ringing at the front gate of the house, and, on going to the door to see what was the cause, she saw a man standing outside, of whom she enquired what was the matter. The person instantly replied that he was a policeman, and said, “For God’s sake bring me a light, for we have caught Spring-heeled Jack here in the lane.” She returned to the house, and brought a candle, and handed it to the man, who was enveloped in a large cloak: The instant she had done so, he threw off his outer garments, and, applying the lighted candle to his breast, presented a most hideous and frightful appearance, vomiting forth a quantity of blue and white flame from his mouth, his eyes resembling red balls of fire. From the hasty glance which her fright enabled her to get at his person, she observed that he wore a large helmet, and his dress, which appeared to fit him very tightly, seemed to her to resemble white oilskin. Without uttering a sentence, he darted at her, and catching her partly by her dress and the back part of her neck, placed her head under one of his arms, and commenced tearing her clothes with his claws, which she was certain were made of some metallic substance. She screamed out as loud as she could for assistance, and, by considerable exertion, got away from him, and ran towards the house to get in. Her assailant followed, and caught her on the doorstep, when he again used considerable violence, tore her neck and arms with his claws, as well as a quantity of hair from her head; her story was fully corroborated by her parents and sisters, and her injuries, which were very considerable, bore unmistakable testimony to the truth of the assault.
