A "vandal-proof" mirror placed in a Watford underpass to deter antisocial behaviour has been smashed.
Watford Borough Council said the mirror was vandalised over the weekend after being installed by a council grant in the subway leading from The Crescent to Watford Fields.
Hertfordshire County Council gave the borough council £55 to install the measure to "provide visibility along the main part of the subway, deter anti-social behaviour and make it a safer area to walk."
The county council also described it as an "anti-vandal proof mirror".
Watford Borough Council said the mirror will not be replaced unless there is another grant to do so.
