WINNIPEG - Police in Winnipeg continue to say they believe a suspected bomb that seriously injured a lawyer is an "isolated incident" and the public isn't at risk.

Investigators released no other details on Friday's incident where Maria Mitousis, who specializes in family law, was hurt by a suspected explosive device that was sent to the office where she worked.

Police say they are still at the scene, and that the 38-year-old victim remains in hospital after being taken there in critical condition.

One source who spoke to The Canadian Press on condition of anonymity said Mitousis lost a hand and was in danger of losing the other one.

A GoFundMe page has been set up online to raise money for Mitousis, stating she "sustained very serious injuries" and "will require financial support as she recovers from this horrific event."

Police are asking anyone with information about the case to contact them.
