Peter Drummond pictured outside Truro Crown Court in Cornwall last Thursday
An anti-terrorism police officer was today convicted of having sex with a 14-year-old girl after he tracked her down using Snapchat mapping.
Peter Drummond, 38, travelled from his house in the Berkshire village of Three Mile Cross to the South West of England twice to have sex with his victim, Truro Crown Court in Cornwall heard.
On one occasion the paedophile let himself in via an unlocked gate at the home the girl shared with her mother and her mother's partner - and on the second visit he climbed through her bedroom window, the court was told.
Drummond was charged with three counts of rape and three alternative charges of sexual activity with a child.
Four of the charges relate to October 2017 while two date to the next month.
Drummond denied the charges but did admit to having 'consensual' sex with the girl, saying that he had no reason to believe she was under the legal age of consent.

After a week-long trial and three hours of deliberation, a jury convicted Drummond today of three counts of sexual activity with a child.
He was found not guilty of three charges of rape. Drummond sighed in the dock as the verdicts were read out.
The court had heard Drummond has worked as a specialist anti-terrorism police officer with the Ministry of Defence since 2006.
Judge Simon Carr will sentence Drummond later today.
Opening the case Fiona Elder, prosecuting, said Drummond befriended the girl on social media, using Kik messenger and Snapchat.
When you have added a friend on Snapchat, you can choose whether or not to share locations with each other on Snap Map. The location only updates when the app is open.
Location sharing options include Only Me, also known as Ghost Mode, which means your location won't be visible to anyone else on the map. Users can turn this on and off, or set a timer if they only want to be private for a short time.
The app also gives users the option to share their location with specific friends. Friends selected are not notified when you choose them.
To edit location settings, tap the ⚙️ settings button in the top-right corner of the Map screen (see below).
Addressing the jury, she said: 'You may think the dangers of social media are highlighted in this case where a child finds herself in a situation that they do not understand and they do not want.
'You may think, having heard the evidence in this case, that this is what happened on this particular occasion.'
She said the girl was distressed previously and met a man on social media who appeared to be supportive.
Ms Elder said. 'Online he had been supportive as she had anxiety. You may want to think that that support from him online had an ulterior motive.'
Ms Elder said police used automatic number plate recognition cameras to show that Drummond's BMW had travelled down and returned from Cornwall on the dates when they had sex.
'He had come to her house using Snapchat mapping,' she added. 'There is no dispute that she did go through a sexual experience. As you will hear, Mr Drummond admits having sexual intercourse with her on these occasions.'
She said evidence of Drummond's DNA was allegedly found in the girl's bedroom.
The court also heard how the girl received £30 from a bank account in the name of P Drummond, which the prosecution said was the defendant's account, so that she could buy a new pair of shoes.
Giving evidence during the trial, the girl's mother told the jury how her daughter had a laptop, mobile phone and iPad and used the devices daily.
She took to the witness stand a day after the judge cleared the court of spectators and press for her daughter to
