34 suspected paedophiles have been arrests across the Thames Valley area.
The move comes after a six-month operation which was co-ordinated nationally by the National Crime Agency, focusing on those using the internet to access indecent images of children.
More than 10 children have been safeguarded as a result of the operation.
ACC John Campbell said: “This operation has seen a great deal of work being done, both in the Thames Valley and nationally, as all the forces involved came together to tackle those who would seek to sexually exploit children.
“As part of the operation, we were provided with intelligence that allowed us to focus our investigations over the past six months, identifying both suspects and victims.
“I hope that this operation sends out a clear message to anyone who seeks to sexually exploit and abuse children and young people using the internet as a medium, that the internet is no longer a faceless void that allows those to prey on the most vulnerable members of our society.”
Nationally the operation involved all 45 police forces in the UK, leading to 660 arrests and the safeguarding of more than 400 children.
It is not known how many of the arrests took place in Milton Keynes.
