Merseyside Police launched a murder probe after the victim, believed to be in his early 20s, was found fatally injured on Lavrock Bank, Toxteth, to the south of the city. Two men were seen driving away from the area on electric bikes, the force said.
Officers were called to the scene at 11.40pm last night, where they found the man “seriously injured” with a gunshot wound to his upper body.
Police performed CPR on the man until an ambulance arrived, before he was taken to hospital. He was pronounced dead shortly after.
In a statement released in the early hours of this morning (Wednesday), Merseyside Police said investigators were now trying to “establish the circumstances surrounding the shooting”.
A murder investigation is now underway and crime scene investigators were carrying out a forensic examination of the scene.
Images from this morning show a police cordon still in place, taping part of nearby Harlow Street off.
Officers are also said to be undertaking door-to-door questioning and examining CCTV footage.
Police believe there to have been two offenders, both of whom were dressed in dark clothing.
The force added that the Home Office would carry out a post mortem to establish the cause of death.
Chief Inspector Col Rooney said: “The investigation is in its infancy and officers are working hard to establish the circumstances surrounding the shooting and to identify those responsible.
“I understand this will be shocking for the local community, but I would like to reassure them that we have increased patrols in the area and we are carrying out a number of lines of enquiry.
“If anyone has any information that would help us with our investigation, or who saw or heard anything suspicious before or after the incident I would encourage them to come forward and tell us what they know.
“I would ask also ask that if anyone has CCTV, or ring doorbell, footage that could help us to get in touch urgently.”
Anyone with information is asked to contact Merseyside Police, quoting reference number 1259 of August 16.
The site of the incident sits near to Brunswick train station, on the River Mersey, in a largely residential and industrial area.
