A man is in a serious condition in Tweed Hospital after apparently overdosing on drugs while in the back of a police vehicle.
About 1.30am yesterday, police stopped a car in Norman Street, Tweed Heads, and arrested the 27-year-old male passenger.
He was taken to Tweed Heads Police Station in a caged police truck.
On arrival, officers noticed a package of drugs in the back of the truck, some of which they thought he might have taken.
They called Ambulance Paramedics, who assessed the man before leaving him in police custody.
But police became concerned about his condition and called paramedics again, who took the man to Tweed Heads Hospital, where he remains in a serious condition.
A critical incident team from Richmond Local Area Command will now investigate all circumstances surrounding the incident.
