A gunman emerged from bushes in an area of parkland and shot two men in the legs at a community bonfire event.
Most residents around Broad Hey, Litherland, did not hear gunshots ringing out due to the frequent bangs of fireworks on Saturday evening, although it is unclear whether the gunman deliberately chose Bonfire Night as a cover for his attack.
Emergency services attended the scene at 11.20pm and the two victims were rushed to hospital with serious leg wounds, although their injuries are not believed to be life-threatening.
