TWO paedophiles - one of whom is HIV positive - groomed vulnerable young boys on the internet.

Anthony Marsh, 53, and Lee Davis, 39, scoured  for their victims, who included youngsters from Barnsley.

Marsh, who used the aliases Tony Taylor and Tony Smith, is HIV positive and pleaded guilty to 34 offences including possessing and distributing indecent images of children, and sexual activity with a child.

Davis used the name James Parkin and pleaded guilty to 20 offences including rape, sexual activity with a child, and taking indecent photographs of a child.

Both men were also jointly charged with conspiracy to commit sexual activity with children, and both admitted their offences at a court hearing last month.

The pair, who are from Doncaster and are both married, searched for impressionable, young, vulnerable boys and arranged to meet them.

Their offences are thought to date back to 2005 and involve boys aged between 13-17 from Barnsley, Doncaster, Rotherham, Sheffield, Hull, Darlington, Birmingham and Preston.

None of the victims contracted HIV.

Detective Inspector Delphine Waring, of South Yorkshire Police, led the investigation.

She said police had worked with others to unravel the 'intricate web' the pair spun around their identities and their crimes.

"Marsh and Davis committed many appalling crimes against young, vulnerable boys over many years," she said.

"The young boys who were the victims of their crimes will continue to receive the support of specialist agencies so they can come to terms with what happened to them and to build successful and happy lives.

"We have also provided support to the families of Marsh and Davis who, let us not forget, are also victims in this case, and whose lives have been changed irreversibly by their behaviour."

They will be sentenced on December 2.
