Cherry Brook Zoo's board of trustees has asked the Saint John Police Force to investigate "possible financial irregularities at the institution."

"After review of financial statements, by an outside accountant retained for that purpose and on advice of counsel, we have contacted the Saint John Police Force and asked them to investigate the matter," interim zoo director Martha McDevitt said in a statement late Thursday afternoon.

The announcement comes just weeks after the sudden departure of the zoo's administrative director, Leonard Collrin, and his wife Lynda Collrin, a volunteer.

The husband-and-wife team, who founded the zoo in 1978 and lived onsite, are no longer associated with the zoo.

"The board of trustees are committed to putting this important institution on a sound and sustainable footing and on the basis of a relationship of trust and transparency.

No further comment will be provided now that police are investigating, it added.
