Two arrested in Devon for inciting riot
Two people have been arrested in Devon on suspicion of incitement to riot.
The 54-year-old woman and 24-year-old man, both from Buckfastleigh, are in police custody.
Their arrests follow police investigations into postings on social networking sites.
Two 17-year-old Plymouth boys, a 16-year-old Exeter boy, a 20-year-old Torquay man, three Newquay men and an 11-year-old Plymouth girl have been visited by police after postings.
Police said they had been given "words of advice" during visits by officers.
Chief Supt Steve Swani said: "We are continuing to monitor social networking sites and would reinforce that we will take robust action against anyone posting material likely to incite crime or disorder."
Police said they were not expecting any trouble on the streets of Devon and Cornwall this weekend.
But there will be high visibility patrols in the towns and cities, and up to 200 special constables were being drafted in.
Twenty seven Devon and Cornwall officers who have been supporting the Metropolitan Police returned on Friday and will be replaced by another 27 officers going back to the capital.
Two other crews of 27 each will remain on duty in Bristol and in Gloucestershire over the weekend.
