Police officers are appealing for information after lights supporting the people of Ukraine were vandalised last weekend.
The damaged lights at Perth' s Queen's Bridge were blue and yellow for Ukraine.
Perth and Kinross Council - who installed the lights - has condemned the act of vandalism as "deplorable".
A spokesperson for Perth and Kinross Council said: "This is a deplorable act of vandalism, made more so as the lights were blue and yellow in support of Ukraine.
"We would urge anyone who has information to contact Police Scotland on 101.”
Officers believe the incident occurred between noon on Friday, March 11 and 8am on Monday, March 21.
Several bridge light fixtures, with reinforced glass, were smashed.
Constable Callum Gibson said: “This is a malicious act of vandalism and it will take time for the lights to be replaced.
“I am appealing to anyone who has any information or knowledge regarding this crime to contact us.”
Anyone with information is asked to call Police Scotland via 101, quoting incident number 1660 of March 21.
Alternatively, you can call Crimestoppers on 0800 555 111 where you can give your information anonymously.
Lib Dem councillor Peter Barrett told the Local Democracy Reporting Service he received reports of damage to the uplighters installed in the ground to illuminate the tunnel - which passes under the Queen's Bridge - connecting Rodney Gardens to Norie Miller Walk.
The Perth City Centre councillor reported the damage to Police Scotland as well as PKC ’s Community Safety and Greenspace teams after local residents and heather garden volunteers reported the damage to him.
Cllr Barrett said: "Someone has smashed all the uplighters. These had heavy duty, thick and toughened safety glass covers which have all been shattered. The vandals would have needed a hammer or heavy object to cause the damage. The sickening thing is that whoever did this has deliberately gone round every single lamp and destroyed each in turn. Words fail me.”
The local councillor said PKC had cleared the area of broken glass for the safety of pedestrians and dogwalkers and their dogs, etc. He echoed the police appeal for information.
Cllr Barrett said: "The police have launched an investigation and I am appealing for information and would urge anyone who knows who did this to contact the police."
