Police from Lethbridge, Alta., are in Fort Simpson, N.W.T., reviewing the local RCMP detachment's handling of a case where a man was taken into custody for public intoxication and later medevaced due to a head injury.

According to Lethbridge police, while Fort Simpson RCMP were on their way to another call, they found a 61-year-old man lying on the street with a group of people around him on July 21. Police say the man was intoxicated and had fallen after a collision with a vehicle.

Paramedics arrived and took the man to the health centre, but he was released after half an hour. He was taken to RCMP cells for being drunk in public. 

RCMP brought the man back to the health centre twice that evening to be assessed. Each time he was discharged back into police custody.

On the afternoon of July 22, police called paramedics to transport the man to the health centre.

Police were told the next day the man had been medevaced to Edmonton for treatment of a head injury.

Lethbridge Regional Police say they are conducting an independent administrative review into whether proper policies and procedures were followed. Police say it's not a criminal investigation or an investigation into police conduct.
