An officer has been charged with misconduct following an investigation into the use of police credit cards.

Detective Sergeant Richard de Cadenet is one of three people to have been arrested as part of a probe into allegations of "irregular usage" of American Express cards by the Met's anti-corruption unit, the Directorate of Professional Standards.

The 38-year-old officer, who is on bail, will appear before City of Westminster Magistrates' Court next week charged with "misfeasance in a public office".

The alleged misconduct relates to spending between July 18 and October 2 last year, Scotland Yard said.

On October 5 last year an off-duty officer was arrested at an address in Cambridgeshire. DS de Cadenet was arrested three days later. He was charged on Tuesday and is due in court on Thursday, April 24.

On December 21 last year a 51-year-old former Scotland Yard officer was also arrested as part of the investigation.

The other two are currently on bail pending further inquiries.
