A Metropolitan Police constable has been charged with 11 counts of publishing and distributing obscene pornographic material.

PC James Addison, who protects Downing Street and other state buildings, was arrested in December alongside three colleagues in connection with the allegations but has now been charged.

The 37-year-old officer with the Diplomatic Protection Group is alleged to have sent videos on his mobile phone in breach of the Obscene Publications Act.

During the course of the investigation, 14 officers have faced either criminal or misconduct investigations into the possession and distribution of obscene images using mobile phones.

No further action was taken against three of the officers arrested during phase one and they remain on restricted duties pending a misconduct investigation.

A misconduct investigation looking into the behaviour of 10 officers is ongoing.

Jenny Hopkins, deputy chief Crown Prosecutor for CPS London, said: "Following a review of the evidence, we have concluded that James Addison, a police constable in the Diplomatic Protection Group, should be charged with 11 offences.

"It is alleged that between 17 February 2013 and 6 June 2013, PC Addison distributed moving images via his mobile telephone, contrary to section 2(1) of the Obscene Publications Act 1959."

Addison is due to appear before Westminster Magistrates' Court on April 23.
