 A POLICE watchdog has asked for a full briefing from North Wales' chief constable after the trial of a former leading officer collapsed. Ex-chief superintendent Peter Bolton was cleared at Chester Crown Court of leaking a confidential police authority report. The trial cost around £150,000. The assistant clerk to the authority, Mr Bolton, who was suspended from his £30,000-a-year job since July, had denied sending a copy of the report to a freelance journalist. But the trial was halted by the judge last week when the court heard many more people could have potentially leaked the report. It was into bullying allegations against former deputy chief constable Bill Brereton. North Wales Police Authority has asked chief constable Richard Brunstrom to provide them with a "full report on all the circumstances" of the prosecution for misconduct in public office. |
