UP TO three more arrests are likely as a result of the Mail's investigation into online grooming, according to detectives.
Humberside Police were given more than 500 pages of print-outs showing the Mail's online conversations with men last year.
For two months, we posed as a vulnerable 14-year-old girl on Prodigits, a website containing several chatrooms and forums popular with teenagers.
Our undercover reporter received hundreds of messages, many of them sexually explicit in nature.
Some men wanted to meet.
So far, one man has been arrested and bailed, pending further inquiries.
Now, Humberside Police have revealed further arrests are likely as they pass evidence on to forces in other parts of the UK.
Detective Constable Adrian Adamson, leading the investigation, has spent hours studying the print-outs.
He said: "We expect to make a further arrest and we intend to pass evidence to two other police forces who may well decide to arrest individuals."
The Mail photographed one man meeting a woman posing as a 14-year-old girl who he met on Prodigits.
The meeting took place opposite the Mail's offices in Beverley Road, Hull.
Some of the men had sent our reporter explicit photographs of themselves, while others requested nude snaps.
Several conversations were sexually suggestive, with some requesting meetings.
Our investigation has won widespread support from concerned readers, as well as high-profile organisations, including the NSPCC, which said parents had been given a "worrying insight" into how easy it is for a child to be groomed online.
Before Christmas, Hull City Council leader Councillor Steve Brady said he was "disturbed" by our investigation, while Hull North MP Diana Johnson, who is also Labour's shadow crime and security minister, described our findings as "shocking" and said parents would be horrified by what we had uncovered.
Newland School for Girls in north Hull, which is not connected to our investigation, has put our coverage on display in its reception area.
In a short statement emailed to the Mail, Metin Guckan, Prodigits' spokesman, said under-18s would not be allowed to access the website.
Prior to our investigation, only under-15s were not permitted to become a member of the site.
However, DC Adamson admitted policing social networking sites was impossible.
He said: "Most websites request a person's date of birth, usually in a drop-down menu.
"But anyone wishing to access such a site will just make up a date of birth. It's virtually impossible to control."
