A SEX worker has been holding X-rated parties from a Brentwood hotel.
An undercover investigation by the Gazette can reveal how two such parties took place on Friday evening at the Holiday Inn, Brook Street.
The woman claims to operate throughout Essex and London advertising her services openly on the social networking website Twitter.
Times and prices are advertised on the Twitter account, including the town the parties take place in.
The account has more than 4,000 followers and converses with other users daily.
Friday's events began with a sold-out group session at 5.30pm at a cost of £80 per person, before a later gathering from 7.30pm costing £40.
Rooms at the 149-room hotel, near to junction 28 of the M25, cost £69 per night.
Attendees had first to register their phone number on an online adult website where sessions can be booked. A text message confirmation is then sent with a promise of an exact location to follow.
We registered on Thursday, July 18 and received a text message the following day asking for confirmation of attendance.
After sending a confirmation, a text message was received on the morning of the party reading: "Venue for tonight is the Holiday Inn Brentwood CM14 5NF. Arrive 15 mins before the start (GB 17.30 Buk 19.30). Text me u have arrived and wait patiently. I will text the room no when we are ready. Don't disclose the number to anyone. Thanks."Men waited outside the hotel, and at the far end of the car park, at 7.15pm until receiving the second text message: "Ok Room 118. Through the door turn immediate right. Don't go past reception."Seven men ranging from their early 30s to early 60s took part in the second event.
They were met by a man in smart attire on the door who took payment and photographed the proceedings on his mobile phone. He reassured those inside that he would be careful to avoid capturing faces in his shots.
A series of graphic images were posted on Twitter later that night. The account is unlocked and can be accessed to anyone with a Twitter account.
Twitter's policy on pornography reads: "You may not use obscene or pornographic images in either your profile photo, header photo, or user background.
"Twitter can suspend an account if abuse is discovered."The revelations follow a 2009 Gazette report, which highlighted six popular dogging sites in Hutton, Warley and West Horndon.
In April this year the town was cited in a Channel 4 documentary, Dogging Tales, as one of the UK's dogging hotspots.
The news comes in the week Prime Minister David Cameron promised to clamp down on the availability of online pornography.
Images from the event, too graphic to publish, have been passed on to Essex Police.
Brentwood Neighbourhood Policing Inspector Paul Wells said: "We are grateful that this has been brought to our attention and we will make relevant enquiries.
"There may not be legislation to deal with all parties involved but there may be relevant legislation pertaining to the use of the building for such a purpose.
"Until further enquiries have been made it would not be appropriate to comment beyond this.
"There are a number of associated risks with this sort of activity, both health and potentially criminal, so we would discourage anyone from taking part."
No money was paid by the Gazette and our reporter did not participate in the party.
