Three police officers were taken to hospital after a car chase through Edinburgh and West Lothian in the early hours of Tuesday.
Officers were called to reports of a car travelling the wrong way on the A720 Edinburgh City bypass at around 1.10am, which later refused to stop.
Road policing officers attended and pursued the blue Vauxhall Astra, deploying tactics to bring the car to a stop on the M9 between junctions 1A and 2.
Three police officers were taken to Forth Valley Hospital to be checked over following the chase.
The motorway was closed at 2am and reopened shortly after 5.30am.
Inspector Stephen Quinn said: “Our enquiries into the circumstances surrounding the vehicle which failed to stop are ongoing.
“I would urge anyone who may have witnessed this vehicle’s movements or was in the area around the time of the pursuit to contact police.
“Also, anyone with dash-cam footage which could assist our investigation should get in touch.
“Anyone with information can contact police on 101, quoting incident number 0115 of October 11.”
