Charlottetown Police say a man was so intent on eluding arrest earlier this week that he jumped into the water and tried to swim to freedom.
Officers tried to stop a car after seeing that it was being driven without headlights turned on early Monday morning.
But they say the driver dove into the water at the end of Great George Street and swam to a boat nearby.
Police say they caught him on the boat and charged him with impaired driving after determining he had twice the legal amount of alcohol in his blood.
