Lincolnshire Police have issued a warning on their website, saying they have received a number of reports from members of the public about social media posts that could potentially incite racial hatred and violence.
This comes in the wake of the Woolwich terror attack on Wednesday, and the subsequent investigation of a property in Saxilby in Lincolnshire.
Police say the posts are currently being investigated and that if they breach the law 'those messages may be monitored captured and robust police action will be considered.'
