A murder investigation was under way today after one man died and another was critically injured in a street gang knife fight. Police who were called to the incident in Gaythorne Road, West Bowling, yesterday found three men with stab wounds – three other people, including a woman, have now been arrested on suspicion of murder. The injured, a 17-year-old, 22-year-old and 24-year-old, all from Bradford were taken to Bradford Royal Infirmary. Surgeons battled to save the 22-year-old but he died shortly before 3am today. The 24-year-old, who also had surgery, remains in a critical condition, said detectives. The 17-year-old was released after treatment for a laceration. Two men, aged 42 and 25, and a woman aged 34 are being held for questioning at different police stations across the county. The murder investigation is being led by Detective Superintendent Tim Forber, of West Yorkshire Police homicide and major enquiry team. Initial reports from bystanders suggest there had been fighting for about 20 minutes between rival black and Asian gangs. One of the men had been stabbed in front of a three-storey terraced house in Parsonage Road which runs alongside Gaythorne Lane, said a witness. Police said although the investigation was still in its early stages, the incident was “not a random attack.”
