A specialist police unit says it's arrested about 300 online paedophiles in the last year - safeguarding more than 400 children.

The Child Exploitation and Online Protection Centre says that includes 60 children who were traced through child abuse images.

The agency's arrested 192 suspects in the last year - before an operation last week, which saw over 100 more arrests in 48 hours, including 2 in Avon and Somerset.
