It's perhaps the lowest-speed police chase ever.
Footage has been released showing police chase a suspected stolen steamroller through residential streets in Bolton. But in this instance the traffic officers reached a top speed of around 5mph.
Police began to pursue the steamroller on Radcliffe Road in the early hours of this morning.
The video shows the vehicle veering from side to side on the road while police followed slowly behind.
The driver of the construction vehicle abandoned it on Raikes Road and then fled through a garden area.
No arrests have been made. Police are trying to find out whether the vehicle was actually stolen.
Anyone with information is asked to contact police on 101 or Crimestoppers, anonymously, on 0800 555 111.
