A disgraced former policeman faces the loss of a prized royal honour.

Last July, Ian Duncan, 46, was sentenced to eight months' jail after he was convicted of indecently exposing himself to a 9-year-old girl in The Warehouse, Levin.

Duncan received the Queen's Service Medal in 1995 for his work as a Wainuiomata community constable.

A Crown spokesman says moves are under way to strip him of that. In July he was stripped of his police long service and good conduct medals.
