FREDERICTON -- The New Brunswick Police Commission has agreed to investigate allegations made against the deputy chief of the Saint John Police Force at the murder trial of Dennis Oland.

Steve Roberge, the executive director of the commission, made the announcement at a news conference, saying the investigation was requested by police Chief John Bates.

He says the allegations in the complaint centre around Deputy Chief Glen McCloskey and testimony at the trial, but the investigation will not begin until the trial is concluded.

Last week, former staff sergeant Mike King alleged in his testimony at the trial that McCloskey suggested he not reveal that McCloskey, who was an inspector at the time, had entered the bloody crime scene where the body of businessman Richard Oland was found on July 7, 2011.

McCloskey denied the allegation when he testified.

The police commission investigation will be conducted by former Fredericton police chief Barry MacKnight.

Dennis Oland has pleaded not guilty to second-degree murder in his father's death.
