PRESS ASSOCIATION -- Two teenagers are due to appear in court in connection with messages posted on Facebook allegedly encouraging people to start rioting.
A 16-year-old boy was arrested on Tuesday afternoon following an operation by Strathclyde Police in the south side of Glasgow.
It is alleged the message posted on the social networking site incited others to commit acts of disorder in the area following public unrest in several cities across England.
He is due to appear at Glasgow Sheriff Court.
Tayside Police confirmed an 18-year-old man was arrested in connection with Facebook entries encouraging others to show up in Dundee city centre with weapons to riot.
The force said it had taken "robust and proportionate action" and was following positive lines of inquiry to identify others who may be inciting people to cause public disorder.
The teenager is expected to appear at Dundee Sheriff Court.
The Strathclyde force said there was no intelligence to suggest there is any trouble planned in the city, and officers will continue to monitor the situation.
Assistant Chief Constable Fiona Taylor, Strathclyde Police Operational Support, said the force would take "decisive action" to prevent anyone inciting violence in the Glasgow area.
She said: "Let there be no mistake, we are ready for any eventuality and will take any action necessary to prevent this kind of abhorrent behaviour."
