Eight people have been arrested on suspicion of possessing indecent images of children.
The men were detained after police raided properties across the North East and North Yorkshire over the last two days. Homes in Gateshead, Washington, Scarborough, Harrogate, Stokesley and Whitby were targeted.
Those arrested are believed to be involved in making, possessing or distributing indecent images of children. A number of computers and mobile phones were also seized.
Spokesmen for both Northumbria Police and North Yorkshire Police said:
"Safeguarding children is a major element in helping us reduce harm to the most vulnerable of our communities.
"Today's activity shows the effective arrangements in place to identify and take action against those we suspect are using the internet for illegal activity and the abuse of children."
"This high-profile national operation shines a light on the daily work of our intelligence teams who support detectives and uniformed officers to bring offenders involved in the possession and distribution of indecent images of children to justice."
A 40-year-old man from Scarborough has been charged on three offences, including engaging in sexual activity in the presence of a child, and possessing and distributing an indecent photograph. He is appearing at Scarborough Magistrates' Court today.
