A serving Scotland Yard officer has been charged with trying to meet a child on the internet for sex.
Christopher Exley, 32, will appear in court on Wednesday accused of planning to arrange a sex offence, the Metropolitan Police said.
He has been suspended from duties but will appear in court on bail.
Exley has been listed to appear at Westminster Magistrates' Court.
Scotland Yard said he was charged with "attempting to arrange the commission of a child sex offence, contrary to the Sexual Offences Act 2003".
The arrest is understood to have resulted from a covert operation at the force.
