The supplied text contains only the headline, navigation material and unrelated promotional links, rather than the article itself. It indicates that John Swinney raised concerns about the possibility of a “lone wolf” terrorist attack in Scotland, but does not explain what prompted the warning or what action was proposed.

Because the substantive article text is absent, no reliable details are available on the timing, source of the threat assessment, relevant security measures, or comments from officials. A fuller summary would require the article body.
