In addition to John Pizer and Edward Stanley, police investigated and/or detained several other individuals in their investigation into Chapman's murder, all of whom were released from custody. On 9 September, a 53-year-old ship's cook named William Henry Piggott was detained after arriving at a Gravesend pub with a recent hand injury and shouting misogynistic remarks. A blood-stained shirt he had left in a local fish shop was quickly traced to Piggott, who claimed that he had been bitten by a woman, and that the blood on the shirt was his own. He was investigated, but soon released from custody.
