VANCOUVER—A senior Vancouver police officer has been ordered dismissed from the force for discreditable conduct after an inappropriate relationship with a junior constable who died by suicide.

The Office of the Police Complaint Commissioner says in a statement the order was made against Sgt. Dave Van Patten but he can request a review of the decision.

It says Const. Nicole Chan killed herself last January and the police complaint commissioner ordered an investigation, which was conducted by the New Westminster police.
