A 10-year-old girl trapped a paedophile when she used her games console to take a picture of him touching her.
, 46, was arrested after the brave youngster showed police the picture which officers described as 'indisputable proof' of his guilt.
He was jailed for three-and-a-half years yesterday at Ipswich Crown Court.
The judge heard Fisher first touched the terrified schoolgirl when she was nine.
She told her mother about the attack but nothing was done about it,
the court heard.
But the twisted predator attacked her again over a year later when she was 10.
Robert Sadd, prosecuting, said the victim's quick thinking prompted her to reach for her games console and use the camera on her Nintendo DS to capture the assault.
He was also ordered to sign the sex offenders register indefinitely.
Fisher was made the subject of a sexual offences prevention order, restricting his contact with children under the age of 16 for the next ten years.
'She was brave enough to come forward and report the incident and give us a full and accurate account of what had gone on.
'Although Fisher initially denied assaulting her, when confronted with the image he had no choice but to concede he had done exactly as she had reported.'
