A road was closed for hours on Saturday as witnesses reported police with "riot shields" going down an alleyway.
Merseyside Police confirmed they were called to Shakespeare Street in Southport at around 3pm on February 25. Officers flooded the street as a large cordon was put in place into the evening.
One witness told the ECHO at around 7pm: "They’ve been here about two hours, around 15 police officers went down the alleyway but they’ve not come back out. There were sniffer dogs and two officers had riot shields.”
