A police officer who posted photos of himself in uniform on a sleazy sex website has been allowed to stay at work.

Traffic officer PC James Appi posted pictures showing him outside Downing Street and posing next to Barack Obama’s presidential limousine.

He reportedly left messages saying he fantasised about having sex on his police motorcycle.

Sussex Police said yesterday that inquiries were under way into his behaviour but that his duties were so far unaffected.

PC Appi is based at the force’s road policing unit at Chichester.

His profile on a swingers’ website reportedly featured boasts about his work escorting powerful figures on the roads, which read: “I work closely with firearms teams doing protection work for VIPs.

Princess Di was my favourite.

I was introduced to her and Charles.”

Pictures on the site showed him outside 10 Downing Street and with the car used by President Obama when he visited London.

The posts on adultfriendfinder.com have been taken down.

The website allows people to post and view profiles for finding sexual partners.

Members are invited to state whether they are single, couples or a group, and whether they are looking for “erotic chat”, a “discreet relationship”, “one on one sex”, “group sex” or “other ‘alternative’ activities”.

PC Appi’s involvement was revealed after a woman contacted a national newspaper to report he had suggested he dreamed of having sex on his motorcycle.

The Sun reported PC Appi as saying: “I was pretty stupid.

But as far as I am concerned it was just a bit of fun.”

He reportedly confirmed sex on his police motorbike was a fantasy but added: “I certainly haven’t done it.”

PC Appi told The Argus yesterday: “I’ve been advised at work not to speak to anybody as I’ve already been set up once.”

A spokesman for Sussex Police said: “We are investigating the circumstances of this officer’s entry on the website.

“At this stage he will not be removed from duty.”

The 43-year-old is a governor at Funtington Primary School in West Ashling, near Chichester.

Ray Knight, the chairman of the governors at the school, said the policeman’s position could be in jeopardy following the revelations.

He said: “I’ll have to have a word with the rest of them and see what we are going to do.”

Councillor Ben Duncan, a Green member of Brighton and Hove City Council who sits on Sussex Police Authority, said: “We have got to keep it in proportion. It would not be appropriate for someone to lose their job over this sort of thing.”
