All six of the mother’s children – three boys and three girls – were moved to a rescue centre, a row of one-storey houses on a quiet path set back from the noise of the main roads.
Trees surround the houses, and the staff have planted orchids by the path.
Next month, Unicef will launch a campaign to educate young people about the risks of the online world.
The UK’s #We Protect project, an international alliance to fight online child abuse, has promised £10m to the campaign.
Authorities considered that operation in 2011 to be a one-off case.
