The Independent Police Conduct Authority has found a police officer unjustifiably and unlawfully used pepper spray on an arrested man in a cell last year.
The intoxicated man had crashed his car on June 23 and was brought back to the station, but was aggressive towards officers who attempted to restrain him.
After the man was placed in the cell by eight officers, one went back in after noticing a pair of handcuffs on the floor and their leg was grabbed by the arrested man.
A second officer entered the cell and pepper sprayed the man in the face and he immediately let go of the leg.
The second officer accepted that it could have been possible to drag the first officer out of the cell, but maintained his use of pepper spray.
