Questions still surround why two scientists were marched out of a Winnipeg lab in 2019, and why they’re being investigated by the RCMP. But the story has links to the Wuhan Institute of Virology, and many experts suspect Chinese espionage. Now, pressure is mounting on the federal government to explain.

In the summer of 2019, two scientists — a husband and wife — were marched out of Winnipeg's National Microbiology Laboratory, the highest security lab in Canada. They were later fired, and are being investigated by the RCMP. 

Questions still abound in this story, but many experts suspect it could point to Chinese espionage. And — particularly because of this story's ties to the Wuhan Institute of Virology — pressure is mounting on the federal government to explain what happened. 

CBC News national reporter Karen Pauls joins us to help unravel the mystery.
