A Book of Condolence is to be opened at Liverpool Town Hall on Thursday 8 October for people to add messages of sympathy following the death of Merseyside Police officer David Phillips.
The neighbourhood patrol officer was killed during the course of his duties in the early hours of Monday morning in Wallasey.
Lord Mayor, Councillor Tony Concepcion, will be the first to sign the book when it opens at 9am.
Cllr Concepcion said: “The death of PC Phillips has shocked and appalled the whole of Merseyside and it is important people across the region are given the opportunity to pay their respects.
“Police officers work every single day to keep each and every one of us safe, and his death is a sad reminder of the risks that they face when they are on duty.
“I would urge people to come along to the Town Hall and sign the book to show solidarity with his colleagues and his family, whose loss is unimaginable.”
It will be available for people to sign each weekday from 9am to 5pm until Friday 16 October.
People can also email a tribute to email@example.com and it will be added, or tweet them to @townhallLpool
