Three Winnipeg police officers had to use an antidote after possibly being exposed to a deadly opioid.
Police said it happened when the officers were at the scene of a car crash in Elmwood on Monday afternoon.
The officers gave themselves naloxone, which is a medication to block the effects of opioids.
Police said they are still waiting for further testing, but all officers were medically treated and released.
An antidote is a substance used to counteract poisoning.
