Jane Alsop reported that on the night of 19 February 1838, she answered the door of her father's house to a man claiming to be a police officer, who told her to bring a light, claiming "we have caught Spring-heeled Jack here in the lane". She brought the person a candle, and noticed that he wore a large cloak. The moment she had handed him the candle, however, he threw off the cloak and "presented a most hideous and frightful appearance", vomiting blue and white flame from his mouth while his eyes resembled "red balls of fire". Miss Alsop reported that he wore a large helmet and that his clothing, which appeared to be very tight-fitting, resembled white oilskin. Without saying a word he caught hold of her and began tearing her gown with his claws which she was certain were "of some metallic substance". She screamed for help, and managed to get away from him and ran towards the house. He caught her on the steps and tore her neck and arms with his claws. She was rescued by one of her sisters, after which her assailant fled.
