Detectives investigating a shooting in Kirkdale have arrested an 18-year-old man on suspicion of possessing a firearm without a certificate on Tuesday 19 April.
He is currently in custody where he is being questioned by detectives.
At around 3pm officers were called to a report that a man had been shot in an alleyway on Rosalind Way.
The 21-year-old man was taken to hospital for treatment to a gunshot wound to his neck. His condition is described as serious but not life-threatening.
It was reported that two males wearing dark clothing were seen running from the offence location towards Westminster Road.
A cordon remains in the area as officers continue to carry out forensic, CCTV, house-to-house and witness enquiries.
At this stage, the shooting is believed to have been targeted.
Detective Sergeant Claire Astbury said: “Although we have made an arrest our enquiries are still ongoing.
“Our officers are continuing to speak to potential witnesses in the area and studying CCTV footage for clues as to why this happened, and most importantly who is responsible so they can be brought to justice.
“We’re keen to hear from anyone we have not yet spoken to who witnessed the incident, or saw or heard anyone acting suspiciously in the area at around 3pm yesterday afternoon.
“You may live nearby or have been passing the area at the time on foot or in a vehicle. Any information you have, or dashcam or CCTV footage, could help us with our investigations.
“Through information provided by our communities and proactive policing operations and tactics, we have seen a decrease in firearms incidents over the past two years.
“We’re determined to keep preventing them from happening so that our communities can continue to live, work and enjoy going out of an evening free from the fear of incidents such as this.
“If you tell us anything you know about this incident, we will take positive action and make Merseyside safer.”
