The woman who sold him naked images of her young son and daughter was jailed for 18 months.
Timmy Duggan and the woman who sold him pictures of her children naked are both to remain indefinitely on a sex offenders register.
Duggan pleaded guilty to paying mothers to get access to their young sons and daughters for his sexual gratification.
He admitted twice sexually assaulting a young girl, encouraging mothers to produce and supply him with naked pictures and videos of their children, possession of “child pornography”, and engaging in a sex act with a mother in the presence of her young child.
A mother of three - who cannot be named - pleaded guilty to seven charges relating to the sexual exploitation of her children.
Judge Elva Duffy said Duggan had engaged in disturbed, depraved, and obscene conversations with a mother in relation to planning to access her child for his sexual gratification.
The judge said the mothers’ actions were a fundamental breach of trust and that instead of protecting their children they were offered up to Duggan for financial reward.
