A police car responding to an emergency was hit by a brick in the latest shocking attack on a force vehicle.
The unmarked car was one of four Merseyside Police vehicles on a "blue light run" through Anfield on Saturday night.
The brick hit the vehicle but narrowly missed the windscreen.
Reporting on the incident on Twitter, Merseyside Police's Roads Policing Unit said: "The consequences if it had hit the windscreen are unthinkable."
The attack came just eight days after a marked patrol car was hit with a brick in Garston.
The vehicle was being driven on Speke Road, near the Horrocks Avenue junction, when two men on an orange and black scrambler bike threw a brick at the back window.
The brick hit an officer, who had to go to hospital with a head injury.
A 23-year-old man from Garston has since been charged with attempted section 18 wounding.
