A man died after allegedly speeding away from police and crashing into a tree on Tumbulgum Road near Murwilumbah around midnight.
Police were called to the location following reports of an intoxicated man.
As police arrived a vehicle sped off from the scene and subsequently crashed into a pole a short distance up the road.
The man driving the car died at the scene; the other man travelling in the vehicle was not injured.
A critical incident team from Richmond Local Area Command will now investigate all circumstances surrounding the incident.
That investigation will be overseen by the Professional Standards Command.
All information will be provided to the Coroner.
No further details are available at this time; however, police are appealing for witnesses to come forward.
