Images of Beechwood Drive, on the Beechwood estate, show several police vehicles protecting a demarcated area.
This area includes several houses and a grassy area opposite, beyond which there are a series of shops, a chapel and a social club.
Comments on social media suggest that locals fear that there were gunshots last night.
Several people living near the scene said they heard what looked like “fireworks” just before midnight.
Police were reportedly present in the area from the earliest hours, and forensic officers were reportedly among those responsible at the scene.
The nature of the incident has not been confirmed.
ECHO contacted Merseyside police for details of the force investigations.
