Halifax police warn public about 'date-rape' drugs stolen from hospital

HALIFAX - Halifax police say a drug that is sometimes used in sexual assaults has been stolen from various parts of a local hospital over the past three weeks.

Police have issued a public warning after 16 vials of the narcotic Midazolam were stolen from the Queen Elizabeth II hospital.

Investigators say the narcotic is a type of benzodiazepine drug that is water soluble, odourless and tasteless.

The police department also advised how to avoid having someone slip the drug into a drink while at a bar.

The warning urges people to watch their drinks being poured by bar staff, or to pour their own drinks.

It also suggests people avoid sharing drinks or accepting drinks from people they don't know.
