This is the dramatic moment which appears to show armed police surrounding a vehicle in the middle of a Sheffield street.
Video sent to The Star shows seven police cars driven by armed officers stopping on Catch Bar Lane at the junction with Leppings Lane in Hillsborough.
The footage, taken from a resident close by, shows one officer climbing over the car for closer inspection.
South Yorkshire Police has been contacted for a comment. They are yet to respond.
This is a developing story and we'll bring you more as we get it.
