Konan Michel Yao, 42, 'was taken into custody' while crossing the border from Manitoba province into the western US state of North Dakota on May 5, said a spokeswoman for the Public Health Agency of Canada, which operates the lab.
 

According to US prosecutor Lynn Jordheim, Yao was detained for carrying unidentified biological materials in vials wrapped in aluminium foil inside a glove and packaged in a plastic bag, along with electrical wires, in the trunk of his car.

Yao said in an affidavit he stole the vials, described as research vectors, from the Winnipeg lab on his last day of work there on January 21.

He told US border guards he was taking them to his new job with the National Institutes of Health at the Biodefense Research Laboratory in Bethesda, Maryland.

US authorities feared their contents could pose a terrorist threat. But tests later showed 'they are not hazardous,' said Jordheim.

'This turned out not to be a terrorism-related case,' he said by telephone from North Dakota. 'It appears to be exactly as he (Yao) said. However, he still faces possible charges for smuggling the vials into the United States.'

Yao, meanwhile, remains in US custody after waiving his right to bail and preliminary hearings, as he awaits a possible grand jury indictment for smuggling, he said.

A Public Health Agency of Canada spokeswoman told AFP Yao 'was working on vaccines for the Ebola virus and HIV, among other things.'

'But he only had access to harmless and non-infectious materials, similar to what you'd find in a hospital or university lab. He did not have access to dangerous materials.'

The Ivory Coast-born scientist is said to have studied at Laval University in Quebec and briefly worked at the University of Manitoba's plant sciences department.
