The Royal Newfoundland Constabulary issued a public advisory after a number of drugs were stolen from a veterinary clinic in St. John's.
Police said the Avalon Animal Hospital in Logy Bay-Middle Cove-Outer Cove on Logy Bay Road was broken into some time Sunday morning between 12:15 and 10:05 a.m.
Two safes containing a "large quantity of drugs," mostly narcotics, and prescription pads were stolen from the site, police said.
The RNC is concerned about the nature and quantity of drugs stolen, and consider their potential availability on the street to be a public safety concern.
One of the most alarming drugs stolen is sodium pentobarbital, which is used in the lethal injection cocktail, as well as to euthanize animals.
Const. Steve Curnew said another of the stolen drugs is ketamine, a fast-acting anesthetic police know is used as the commonly-known 'date rape' drug.
"People can administer this drug fairly unknowingly to someone — an unknowing person — and we've had reports in the past, not so much of ketamine, but we have had reports in the past of these types of drugs being administered in local establishments," said Curnew.
Police ask anyone with information to contact the RNC at 709-729-8000 or anonymously at Crime Stoppers at 1-800-222-8477.
