PRESQUE ISLE – Presque Isle police are investigating the theft of more than $2,000 worth of drugs and some cash from the Presque Isle Animal Shelter.

Sgt. William Campbell said Thursday they had no arrests, but are pursuing leads in the break-in that occurred Tuesday night.

An employee of the animal shelter reported the break-in Wednesday morning.

Campbell said 24 kinds of drugs were taken.

The greatest concern to police was the theft of sodium barbital, a drug used by veterinarians to euthanize animals. Campbell said small doses of the substance could be fatal to humans.

There was minimal damage to the building, and animals there were not disturbed, the officer said.
