Five arrests have been made in Wales over the alleged use of social media sites to encourage disorder following the riots in England.
Two men from Cardiff, both aged 24, are in custody after being arrested for inciting criminality by misusing Facebook.
They were arrested as part of an ongoing investigation into a small number of incidents in the city overnight on August 9/10.
A 31-year-old man from Newport has been arrested on suspicion of intentionally encouraging or assisting the commission of a public order offence. He remains in police custody.
A 21-year-old man from Bangor was also arrested for ‘incitement to commit an indictable offence’. He has been released on bail and is due to appear before Caernarfon Magistrates’ Court on August 23.
Meanwhile, a 27-year-old man from Ebbw Vale was cautioned for sending a malicious communication via a public network.
Gwent Police have urged people to use social media responsibly and not fuel rumours.
Deputy Chief Constable of Gwent Police Jeff Farrar said: “I have no doubt that many of the pictures and reports from across the UK within the media will provoke concern among our communities.
“I want to reassure them that, in the Gwent force area, we have not experienced major unrest as seen elsewhere but what we have had is irresponsible use of social media which has caused unnecessary fear and anxiety in the community.
“We have already made arrests and will continue to do so. We want people to know that we not only police the streets in Gwent, we police the online community as well.
“Meanwhile, as usual, our priority is to protect and reassure communities in Gwent. Officers will be out and about and available to speak to anyone who has any concerns, alternatively members of the public can call 101 or keep updated via facebook or twitter.”
Detective Chief Inspector Andy Davies of South Wales Police said: “South Wales Police is continuing to monitor social networking sites and anyone who uses them to attempt to generate disorder in our communities will be traced and dealt with.”
