Destructions reported to Merseyside Police, which are being investigated using video footage, include railings at the Hillsborough Monument that were demolished and thrown into the river, and damage to the Art Deco globe lamps overlooking Memorial Garden.
Hillsborough Memorial Garden in Wallasey was horribly damaged and 26 windows were smashed in City Hall.
The vandalism of part of the Memorial Garden, dedicated to the Hillsborough families, is devastating.
Janette Williamson, a cabinet member of the Wirral Council for Finance, said: “There are simply no words to describe the thoughtlessness of such acts.
The total cost of the damage is already over £5,000, but is likely to be much higher, as so far only the bill for window repair has been taken into account.
In the town hall itself, 26 first floor windows were smashed.
“At a time when the community has pulled so powerfully together in these times of unprecedented crisis, this feels like a kick in the teeth.
“The damage that now needs to be repaired with public funds from our already strained budget is bad enough, but the destruction of part of the Memorial Garden dedicated to the Hillsborough families is devastating.
Paul Harrison, Community Policing Inspector for Merseyside Police, said: “Criminal behaviour of this nature will not be tolerated and we will work with our partners on Wirral Council to find the person(s) responsible.
“I appeal to anyone who has witnessed or has information to contact us either via DM [direct message]@MerPolCC or @CrimestoppersUK on 0800 555 111”.
