The statement continued: “As a complaint has been received, it would be inappropriate to comment further at this time.
“While we look to establish the full circumstances of what happened, we would urge people not to speculate and avoid sharing rumours or misinformation.”
The incident happened the night before Halloween, on what in Merseyside has become known as “Mischief Night”.
Merseyside Police’s statement added: “We are determined to protect our communities from the sort of appalling behaviour that we historically see at this time of year.
“We have a contempt for criminality and a commitment to cracking down on people committing serious offences in Merseyside.”
