Sûreté du Québec police are asking for the public's help to find an inmate who escaped after receiving treatment at the Gatineau hospital and injuring a staff member.
The inmate is 22-year-old David Harvey, described as 5'11" and 159 pounds, with brown hair and brown eyes.
Harvey was serving a sentence at the Hull detention centre.
He was wearing a black coat, black pants and walking boots when he escaped.
The Quebec provicinal police have teamed up with the Gatineau police to look for him.
Police speculated he might try to hitchhike to Montreal, his hometown.
Gatineau police did not say how Harvey injured the staff member.
The public was also warned to call 911 if they see Harvey, rather than try to approach him.
