It's not uncommon these days for news organisations to lazily use Twitter as a source in this way. Actually contacting the police force which had supposedly escorted voters would involve actual reporting.
Given no one has commented on why they down voted, this is just speculation on my part based on what I've seen elsewhere on HN.
