Vandals attacked a fire station while firefighters were called out to an incident, with nine vehicles damaged by the thugs.
The incident happened around 12.30am this morning at the Fire Station, near the Boghall Roundabout.
While fire crews were attending an incident within the area, the facility had windows smashed and a fire community vehicle damaged.
In addition eight personal vehicles of the firefighters were also damaged.
Officers are now conducting local enquiries to identify those responsible and anyone with information is asked to come forward.
Chief Inspector Paul Cameron, Local Area Commander for West Lothian said: “This has been a mindless act of destruction targeting the local fire service while the crew was out assisting the community.
“In addition to the damage sustained to fire officers’ cars, a community fire vehicle was also damaged and will require repair, taking the vehicle out of service which deprives the community of this resource.
“We are keen to hear from anyone who remembers seeing anything suspicious around the station in the early hours of Wednesday morning.
“Similarly, anyone with any further information relevant to this investigation should contact police immediately.”
Those with information can contact Police Scotland on 101 or alternatively, the charity Crimestoppers on 0800 555 111.
