Detectives believe these men could have information that would help them solve a series of attacks by a hammer-wielding gang.
A taxi driver was hit with a hammer and two shops targeted in robberies during a spate of incidents spread across three Merseyside boroughs in less than six hours.
Police believe the offences are linked and today released CCTV of three men they would like to speak to as part of the investigation.
The first incident took place at around 5pm on Friday, August 21, when a group of males walked into Go Local on Waddicar Lane in Melling.
One of the gang picked up a crate of lager but was asked for ID by a shop assistant.
He then raised a lump hammer and said something to the worker before the group fled with the crate.
At around 6.25pm, a male shop assistant saw the window at Dillon's Food and Wine, on Warbreck Moor, being smashed with a hammer.
A male then walked into the shop with the hammer and asked for the till to be opened.
When the assistant refused, other males then started to pull items from shelves and the yob with the hammer smashed items in the shop.
Cigarettes were stolen in the incident.
Then, at around 10.30pm that same night, in Sefton Close in Kirkby, a taxi driver was sitting in his car when a male knocked on his window and asked to be taken to Liverpool.
The taxi driver told the male he could only take pre-booked fares and locked the doors.
