Officers have since attended the scene where they found damage to a front door consistent with gunshots.
It is believed to have been a targeted attack and detectives are trying to track down those responsible.
Nobody was reported as being injured and house-to-house and forensics enquires continue.

Speaking of the incident in Huyton, Detective Superintendent Richie Salter said: “At this stage we are looking to establish exactly what happened and find those responsible and the weapon used.
“We believe that this was a targeted attack, and was unreported by anyone locally at the time.
“If you saw or heard anything at around 6pm on Friday, or are aware of the issues or criminality that sit behind this shooting and have yet to come forward, please do so, whether directly or anonymously via Crimestoppers.
“We understand the fears people feel in coming forward, but your CCTV, dashcam or other information may be vital in tracking down those people reckless enough to fire a gun towards someone’s home.
