A DEPRAVED loner's filthy hoard of child porn and bestiality was discovered after he left his phone on a train.

Gordon Marshall, 54, surfed the internet for revolting images of girls as young as four and one photo showed a baby being defiled.

Marshall, who jumped police bail and fled to Torquay for 15 months, was arrested after two women handed his phone in at Shipley police station.

Marshall, of no fixed address, was held in custody for three months after he was caught in the seaside town in April.

Today he pleaded guilty at Bradford Crown Court to 22 offences of possession of extreme pornography and making indecent photos of a child.

Prosecutor Duncan Ritchie said more than 3,200 illegal images were found on Marshall's phone and two laptop computers.

Marshall, who has a long grey beard, leaned heavily on a wooden walking stick in the dock, as Judge Jonathan Durham Hall QC said: "This is an extremely troubling case."

The court heard that Marshall had two convictions for indecent exposure in the 1980s and was interested in sex acts performed in public.

Sites accessed by him included "Pre Teen Sex Videos" and "Dogging In Leeds".

In mitigation, Tom Rushbrooke, solicitor advocate, said the probation service was prepared to assess Marshall for a place in a Bradford hostel.

He was a loner who suffered from a number of health problems.

Judge Durham Hall said there was "a gaping hole" in his sentencing powers.

If he jailed Marshall for the short sentence permitted under the law for "simple possession" of the images, he would soon be released back into the community on a limited licence period and having had no treatment.

Instead, he sentenced him to a three-year community order, with intensive supervision, including taking part in the Sex Offender Treatment Programme.

A ten-year Sexual Offences Prevention Order bars Marshall from any internet use unless it can be checked on by the police.

He must also sign on the sex offenders' register for five years so the police can keep track of him.
