LONG investigations into the actions of police officers can see their mental health plummet and affect their families, the Chairman of Wiltshire Police Federation warned. Mark Andrews believes The Independent Office for Police Conduct, which is in charge of investigating the actions of police officers, needs to be held to account for the “unacceptable” amount of time it can keep officers under scrutiny. Mr Andrews said that while his colleagues have no objection at being held accountable for their actions, the IOPC and its investigators spend too long scrutinising their work - sometimes years. Home Affairs Select Committee MPs are looking into the IOPC’s timescales for investigating police conduct.
