A detective working in a child abuse investigation unit is due in court charged with child sex offences.
Metropolitan Police Detective Constable Chris Maitland, 40, who works in the force's sexual offences, exploitation and child abuse command, faces 14 charges in total, Scotland Yard said.
He will appear at Westminster Magistrates' Court on Friday to answer two charges of sexual touching a girl aged under 13, five of making an indecent image of a child and seven of making an indecent image of a child.
Maitland, who is in custody, was originally arrested in November on suspicion of possession and distribution of indecent images of children, and was arrested again on Tuesday on suspicion of sexual touching, a Scotland Yard spokesman said.
He has been suspended from duty.
