A former teacher and accountant has been jailed after downloading more than 150,000 indecent images of children.
Joseph Wilson, of Stonegate House, Stone Street, Bradford, was already on the sex offender's register and served a prison sentence for similar crimes in 2009.
His offending came to light last May, when police executed a warrant to search a flat, with a number of computer items removed.
Wilson was released under investigation and then re-arrested in February this year and further items were seized. Bradford Crown Court heard he had continued to download images - even after his first arrest in May.
He was handed a three-year sentence and will be subject to a sexual harm prevention order.
