The man suspected of gunning down a Canadian reservist then storming into Parliament Hill on Wednesday had a criminal record in Vancouver, and had been deemed a “high-risk traveller.”

Court documents show Michael Zehaf Bibeau, born in 1982, was charged in a 2011 Vancouver robbery, though he was only convicted on a lesser charge of uttering threats.

Zehaf Bibeau was sentenced to one day in jail after serving 66 days pre-trial, which counted toward his sentence. He was also ordered to pay a $100 victim surcharge.

Records show he was given a psychiatric assessment and found fit to stand trial.

When asked for additional details, Vancouver police would only confirm they are working with B.C. RCMP to assist an Ottawa police and RCMP national division investigation.

"Due to the ongoing investigation, there is little information we can share at this time," Sgt. Randy Fincham said in a statement.

CTV News has also learned that Zehaf Bibeau was deemed a “high-risk traveller” by the Canadian government prior to Wednesday’s deadly shooting.

A source confirmed that his passport had also been seized, but couldn’t say how long ago.

On top of his conviction in Vancouver, Zehaf Bibeau had a long record of petty crimes in Quebec, spanning Montreal, Laval, St.-Jerome and Gatineau.

His most serious charges were for robbery and a weapons offence in 2003. His last recorded crime in the province was for marijuana possession in 2006.

A former neighbour in Quebec said Zehaf Bibeau went to a private boys’ school and had good parents and a nice home.

He was born in Canada to a Susan Bibeau, a public servant who worked in the Committee on Immigration and Refugee Board.
