SUMMERSIDE, P.E.I. - A one-time deputy police chief in Prince Edward Island, who was also past-president of a local Mothers Against Drunk Driving chapter, has been sentenced to five days in jail on a charge of impaired driving.

David Griffin of Summerside pleaded guilty in provincial court.

Griffin was a 39-year veteran of the Summerside police force, and was president of the East Prince chapter of MADD when he was charged on July 31st.

The court heard that at the time of the arrest, Summerside's blood-alcohol level was double the legal limit.

Defence lawyer David Hammond says Griffin struggled after facing a lawsuit that accused him of sexual harassment in the late 1990's.

Those charges were eventually dismissed, but Hammond says the court battles that followed took their toll.
