Two men have been arrested after six people were injured in a crash involving three cars on the M1.
The crash, which happened last night near Lisburn, initially involved two cars before a third car crashed into the other vehicles.
The motorway was closed on the westbound side between Sprucefield and Moira but has since reopened.
Two men have been arrested on suspicion of a number of driving offences. One has been released on bail while the other remains in police custody.
Six people have been taken to hospital for treatment.
Police have appealed for anyone who may have witnessed the incident or have dashcam footage to contact them on the non-emergency number 101.
