A child porn "addict" flouted a judge's order by seeking out more illegal images.

Keith Andrew Bell, 46, was originally sentenced at Carlisle Crown Court in 2014.

Bell admitted a dozen crimes having downloaded more than 1,000 indecent photographs of children - the youngest aged just one - during an eight-year period.

Almost 150 of the images were classed in category A - the most serious.

Bell was handed a suspended prison term by a judge who opted to impose a "constructive" sentence having heard mitigation. Bell was placed under probation service supervision for two years, and ordered to attend an intensive sexual offences behaviour programme.

In addition he was made subject to an indefinite sexual offences prevention order.

But despite attending the rehabilitation course, Bell returned to his criminal ways.

Between March 2015 and late last year, he downloaded 50 illegal images of "pre-pubescent" teenage girls. Seven were classed as category A.

Bell's latest round of criminal conduct was uncovered after police visited his then home near Carlisle and seized a mobile phone.

He was jailed for 10 months at the crown court today having admitted three counts of making an indecent photograph of a child and one possession offence.

Judge Peter Davies learned the original prevention order resulted in software being fitted to his computer equipment, allowing police to monitor his online activity.

However, Bell had bought an internet-enabled mobile phone "specifically" to carry out further offending.

A probation officer's report on Bell concluded the original court order "does not seem to have had a deterrent effect".

Bell said he "didn't see the benefit" from the behaviour programme.

"He admits to significantly lying about his problem [to the course administrator]," stated the report, and was still "struggling with a sexual addiction to children throughout the programme".

Mark Shepherd, defending, said Bell described his criminal activity as an "illness".

"This is what he feels it is. It has blighted him for many years," said Mr Shepherd.

Bell, of Upperby Road, Carlisle, was now keen to seek professional help.

But, sending him to custody, Judge Davies said: "You describe it as an addiction. It appears to me that it is a persistent and routine habit and there is precious little evidence of any motivation to rid yourself of that habit."
