Two Doncaster paedophiles are today facing lengthy prison sentences after they admitted dozens of sex offences against teenage boys.
The men - who were not friends - went online to exchange details about some of the boys they targeted.
Anthony Marsh and Lee Davis committed sexual acts with the teenagers and also made indecent videos after grooming them over the internet, often using false names.
Marsh went by Tony Taylor or Tony Smith, and Davis used the alias James Parkin.
They appeared at Sheffield Crown Court yesterday and pleaded guilty to a total of 55 charges committed since 2003.
Other charges are still pending and the prosecution will decide in the next fortnight whether there will need to be a trial on those matters.
If not, the defendants will be sentenced in December.
Marsh, aged 53, a kitchen salesman of Menson Drive, Hatfield, stood in the dock - and Davis, 39, of Rowena Road, Conisbrough, gave his pleas via videolink from HMP Doncaster, where he has been on remand since his arrest earlier this year.
Marsh pleaded guilty to 35 offences and Davis said he was guilty of 21 offences.
One of the offences admitted by Davis is the rape of a 13-year-old boy in 2007 or 2008.
They both admitted a joint charge of conspiring to commit sexual activity with children by exchanging contact details to facilitate meetings for the purpose of committing sexual offences, between 2004 and May this year.
The other offences include sexual activity with a child, possessing indecent images, taking indecent videos, and meeting a child after grooming.
A total of 10 boys - mostly aged 13, 14 and 15 - were victims and four were abused by both men.
Their defence counsel said they would be seeking psychological reports and both men were remanded in custody until sentence.
The Recorder of Sheffield, Judge Julian Goose, QC, placed them on the Sex Offenders’ Register immediately.
None of the boys was in court for the hearing.
