Boys, 12, Suffer 'Significant' Injuries After Substance Thrown At Them
Two 12-year-old boys have suffered burn-type injuries after a substance was thrown at them.
The children were attacked in Granitehill Road in the Northfield area of Aberdeen at around 8pm on Wednesday.
They suffered ''significant injuries'' and were taken to Royal Aberdeen Children's Hospital for treatment.
Police have launched an investigation into the incident.
The area was cordoned off as officers examined the scene.
Investigations to identify the substance are also under way.
The incident took place near the Coral bookmaker outlet.
Specialists from the Scottish Fire and Rescue Service have also been at the scene to help identify the substance and clear it away safely.
Officers want to trace and speak to two youths of a similar age to the victims who have been described as wearing dark clothing.
Detective Inspector Allen Shaw, who is leading the investigation, said: ''This has been a shocking and despicable incident against two young boys who have obviously been left upset and shaken by what has happened to them.
''They have been left with significant injuries and were taken to the Royal Aberdeen Children's Hospital for treatment.
''Extensive inquiries are ongoing to trace those responsible and we are working with our colleagues in the Scottish Fire and Rescue Service as part of our investigation.
''There will be a police presence in the area for some time, however the scene where this incident happened has been examined and I can assure the public it is safe.
''I would appeal for anyone with information about the incident, whether you were in the area at the time or know anything about it, to please get in touch.
''You can contact Police Scotland on 101, via the Police Scotland website or via the charity Crimestoppers on 0800 555111 if you would prefer to remain anonymous.
''I can assure the local community that all resources available to us will be used to trace those responsible. It won't be tolerated.''
The development will include an urban craft distillery, visitor centre, bottling plant, bar and bistro as well as the company's head office.
The Scottish singer was moved by a report he saw on CNN.
The three communities are looking to increase tourism.
