Three policemen and a retired police officer were arrested in an inquiry into fraudulent activity at the Police Federation of England and Wales. Surrey Police are investigating the transfer of £1m to a charitable account last August. One of those arrested quit as federation vice-chairman earlier this week. Two of the men are Met police officers on secondment. The organisation represents thousands of constables, sergeants and inspectors. Surrey Police's economic crimes unit were involved in the probe and are contacting the Charities Commission. Meanwhile a detective constable from a London unit, which investigates rapes, serious sexual violence and child abuse, was charged with a string of child sex offences and suspended from duty. DC Chris Maitland was originally arrested last November, and has now been charged with two counts of sexually touching a girl under 13, five counts of taking indecent images of children, and seven counts of making indecent images of children.
