A New Westminster police internal investigation into Const. Jeffrey Klassen will resume now that he has been sentenced.New West police say delays in Klassen's criminal trial prolonged the opportunity to complete the investigation. Last Friday, Klassen was given a conditional discharge, a year probation and ordered to perform 100 hours of community service for assaulting a Surrey newspaper carrier Firoz Khan in the early morning hours outside the Hyatt Regency Hotel in downtown Vancouver in January 2009.The investigation is being carried out by the Professional Standards Unit of the New Westminster Police Service (NWPS). Klassen had been suspended with pay when criminal charges were laid, but the police board discontinued his pay two months ago.A spokesman said the NWPS will not comment on the case until the conclusion of the investigation.
