Police in Ross-shire are warning that ant-social behaviour will not be tolerated after a series of incidents involving youths, particularly in the Dingwall, Muir of Ord and Conon Bridge areas.
Local communities have raised concerns - while officers have seen a rise in anti-social behaviour in recent months.
These incidents have included vandalism, fire-raising, theft, food being thrown at passing vehicles and youths gathering in large groups, causing concern to other members
of the community.
There has been more than 20 similar calls in December alone.
Officers are now urging those involved to think about the consequences of their actions - while also urging parents to be aware of what their children are doing.
Sergeant James Maciver said: "We want young people to think about what their behaviour could lead to.
"It may seem like a joke at the time but many of these recent incidents could lead to a criminal record and have a have a serious detrimental effect on your future.
"Safeguard your own future and have a think about what you are getting involved in.
"Anyone found to be committing an offence will be dealt with in the strongest terms - remember you might not have been the one to directly commit the offence but if you’re part of a group and an offence is committed then you’re all potentially all equally guilty.
"To parents and guardians, I would urge you be aware of where your children are and what they are doing to prevent them becoming involved in anti-social behaviour or any other wider forms of criminality."
Sergeant Maciver added: "These incidents take place in the communities in which we all live.
"Numerous voluntary groups put their own time, effort and money into keeping our town and villages clean and tidy, making them places that everyone should feel proud to be a part of
"However, incidents such as we have been dealing with recently undoes this hard work through split second acts of complete mindlessness and total disregard for other people’s property and feelings.
"Should your child or children be identified as being responsible they will be dealt with accordingly and in the strongest terms."
Anyone with concerns about anti-social behaviour can contact Police Scotland on 101 or 999 in an emergency situation. You can also pass on information anonymously via Crimestoppers by calling 0800 555 111.
