Avon and Somerset Police report that they were called out to deal with a severed hand on the motorway. The discovery was confirmed by their traffic officers in Highways and could have led to an extensive investigation.
That was until the police officers took a look for themselves and realised that it was a plastic hand. Emergency averted!
The force was happy to share its narrowly-averted embarrassment.... under the hashtag #anyoneneedahand of course.
