A Cardiff teenager has been arrested by police investigating an 'offensive and threatening' social media message following the death of Leeds schoolteacher Ann Maguire.
The 16-year-old boy was arrested yesterday by South Wales Police after members of the public raised concerns with West Yorkshire Police.
He was bailed pending a psychiatric assessment.
Two other people have been arrested in relation to messages allegedly posted on social networking sites after Mrs Maguire was fatally stabbed on April 28th.
