A British teacher has been arrested in Valladolid, north-west Spain for allegedly storing and sharing sexual images of children.
It is suspected that the Manchester born teacher was using a cloud storage system to keep and share images of children, including his students.
As part of an Interpol investigation, illegal files were discovered to be being sent from an email address in Spain.
A large number of sexually explicit files involving minors were found at the home of the teacher, officers say.
