A beach brawl in Broughty Ferry involving up to 100 youngsters left a teen with facial injuries.
A police car was also put out of operation after it was vandalised during Monday night’s carnage.
Police say inquiries into the incident, which involved between 80 and 100 youngsters, are still ongoing.
Despite rumours circulating, officers are keen to reassure locals they have received no reports of anyone being stabbed.
However a 15-year-old male did sustain an injury to his face during the disturbance, which was reported at around 6.50pm.
Rubbish left on Brook Street – some dumped in flower planters – was cleared up on Tuesday morning as the clean-up operation got underway.
Police patrols in the area are also being stepped up in a bid to provide reassurance and curb anti-social behaviour.
Chief Inspector Ross Fitzgerald said: “We want everyone to enjoy these open spaces safely.
“Disruptive and criminal behaviour is not acceptable.
“I can assure you that work is ongoing to ensure those involved are located and identified, with anyone involved in criminality being dealt with robustly and charged in respect of any criminal behaviour committed.”

He added: “The vandalism to the police vehicle now renders that resource inoperable, depriving the local community of important resources as we continue our efforts to keep our local communities safe.
“Parents are encouraged to be aware of where their children are and what they are doing in the evenings.
“Members of the public will see an increased police presence in the Broughty Ferry area as local officers are supported by those from national divisions, in order to provide reassurance and deter any further acts of antisocial behaviour.”
The chief inspector is urging anyone with information to call 101 quoting incident number 3128.
Locals took to social media to complain they were forced to leave the beach because of “steaming drunk” youngsters.
One witness told The Courier: “I went to the beach tonight with my two little girls and my partner and while we were there there were multiple groups of youths.
“I reckon there must have been over 100, aged between around 12 to 18.
“They started running, shouting, scrapping and fighting.
“This went on from the moment we arrived until the moment we left.
“We actually witnessed them all fighting, throwing bottles and someone said weapons were involved.
“There were a lot of young people injured. Young children were crying because they were so scared – it was just awful.”
