A counter-terror police officer has been found guilty of child sex offences after he arranged to a meet a 13-year-old girl for sex.

Francois Olwage, a detective constable with Metropolitan Police's specialist operations unit, thought he was chatting online to a teenage girl but it was actually an undercover officer.

He arrested at a McDonald's in Basingstoke as he was about to buy a McFlurry ice cream to take to his meeting with "Caitlin".

Two condoms, lubricant, erectile disfunction tablets and a box of Ferrero Rocher were found in his bag.

Olwage, 52, from Stevenage, set up the meeting after a fortnight of explicit conversations online and using WhatsApp.

His trial at Winchester Crown Court heard he was meant to be "on duty working from home" when he arranged the meeting last October.

Olwage said he did not believe he was really going to meet a teenager and claimed he thought it was an adult "playing out a fantasy".

He denied sexual interest in children but was convicted of attempted sexual communication with a child, attempting to cause/incite a girl aged 13 to engage in sexual activity, and attempting to meet a girl under the age of 16 following grooming.
