Gunmen fired at a West Derby house in an apparent mistaken identity shooting.
Officers were called to Lingmell Road at around 8.20pm on Easter Sunday following reports of damage caused to the window of the property.
Patrols confirmed the damage was consistent with a shotgun discharge.
Two men were seen on an off-road bike in the area at the time of the incident and detectives are keen to trace them or anyone who saw them in the area.
The house’s occupants were not injured but have been left shaken.
Neighbourhood patrols have been stepped up in the area to provide reassurance to local residents and house-to-house and CCTV enquiries are being carried out.
Chief Inspector Paul Sutcliffe said: “This was an extremely frightening incident for the occupants.
“Thankfully no-one was hurt but this was an incredibly dangerous and reckless act and we are doing everything we can to trace the criminals responsible.
“The investigation is in its early stages and the motive for the attack is unclear however we believe this is a case of mistaken identity.
“Criminals involved in gun crime have no regard for anyone else and I would urge the local community to come together to help us take a stand against the use of firearms and violence on our streets and report anything they saw or heard to us so we can take action.”
Anyone who saw or heard anything suspicious is asked to call the Matrix guncrime hotline on 0800 230 0600 or Crimestoppers, anonymously, on 0800 555 111.
