The fact that no mention of the vehicle at fault suggests maybe the police car because no police force likes admitting to one of their officers making a mistake.
https://www.bbc.co.uk/news/articles/c51zp43e8z8oTwo officers have been injured after a police car responding to an incident crashed with a taxi in Birmingham.
The crash happened on St Chads Queensway earlier on Saturday, which led to the road being closed at Snow Hill Queensway.
The officer "driving the car which was responding to an incident, had to be cut out of the vehicle and has been taken to hospital", police said on X.
The other officer received minor injuries.
"The taxi driver and a passenger, thankfully were uninjured," West Midlands Police added.
