Armed police were called in to protect a lorry that spilled £1 million into the road.
Lorry spilled cash everywhere
The Loomis vehicle was surrounded by police after crates carrying coins littered the road in Swindon, Wiltshire.
Sergeant Gemma Vinton, who was among the first on the scene, said: ''At the moment we are assisting with traffic control and trying to get to the bottom of what's happened.
''My understanding is no other vehicles have been involved in the incident.
''I am expecting there to be traffic disruption for the next hour to hour-and-a-half. Obviously we will remain here whilst the vehicle is recovered.
''This is certainly not something I have come across before.''
