Police are looking for eye witnesses following a serious crash in Southport involving three vehicles.
At around 4.25pm on Friday 26 March, a police car signalled for the rider of a Suzuki motorbike to stop on Norwood Road.
The bike continued to the junction of Peel Street where it was involved in a collision with a black Ford Fiesta, which was in turn in collision with a white Ford Transit van.
The rider of the bike, a 27-year-old man, and the pillion passenger, a 22-year-old man, were taken to hospital. The rider is being treated for serious but non-life-threatening injuries, and the passenger is being treated for minor injuries.
No-one else was injured in the collision. The Force's Roads Policing Unit has now opened a full investigation.
