Three teenagers have been arrested in connection with a disturbance that left a 14-year-old boy injured in Angus.
The youths, aged 13, 15 and 17, have been charged over the incident that took place in Kirriemuir on Sunday evening.
Police have warned the public that anti-social behaviour will not be tolerated.
Officers say extra patrols will be carried out in the area over the weekend to ensure there is “no repeat of last week’s scenes”.
Sergeant Garry Miller said: “The vast majority of youths are not involved in crime or anti-social behaviour but unfortunately a minority are.
“We don’t want to discourage youngsters from meeting with friends in public places as they have every right to be there but this must not impact on the safety and rights of others to do the same.
‘‘Parents also have a role to play in ensuring that their children are safe and behaving appropriately.
“I would urge all parents to speak with their children about where they’re going, who they’re with and what they’re doing.”
