The woman, an employee at the bank, is reported to be in serious condition in hospital.

Niagara police originally reported the incident as a violent bank robbery at an RBC branch on Martindale Road, but later said the attack was targeted.

Their concern for further violent was such that the St.Catharines hospital the victim was taken to instituted precautionary security measures.

Police have identified their suspect as Justin Kuijer, 43, of St. Catharines. He is wanted for attempted murder. Police say he is considered armed and dangerous.

Police say the man fled in a grey 2009 Pontiac Montana van, license plate BYTE392.

He's described as a white male, about 35 years old, with a tall, thin build. He has a beard and longer dark hair. He wore a black touque and coat, boots and possibly an orange sweater. There is a second scene that police say they are also holding as part of the investigation.
