Social media riot messages: North Yorkshire police free six
Six men arrested in North Yorkshire over postings on social networking sites during disorder across England have been released without charge.
The men, aged between 18 and 38, were held on suspicion of posting comments inciting violent or criminal behaviour.
Officers have also visited a number of people to give "strong words of advice" over comments which were not deemed to warrant a criminal investigation.
North Yorkshire Police said it took any threats posted online very seriously.
Temporary Deputy Chief Constable Tim Madgwick said: "Used responsibly, the internet has huge benefits, but police would like to remind people who use social network sites of their responsibilities.
"Many people have been distressed and unnecessarily worried by rumours circulating as a result of postings on the internet.
"Our stance against such behaviour has been clearly demonstrated over the past few days.
"While no-one has faced any criminal charges in relation to these messages, we hope it acts as a warning now and into the future, as to how serious the police take such threats."
