A man has been jailed after a horrified train passenger caught him watching child sex abuse videos in full view of other commuters. David Johnson, 35, was on a train from Stafford to London when he was seen messaging a contact asking, 'What kinds of videos do you like? I have all kinds,' before adding: 'Just kids videos.' He then opened a video involving a young child, leaving the passenger seated behind him shocked.
The witness messaged his own partner to report what was happening. When he looked back up, Johnson was watching another video showing an even younger child being abused. The man then moved carriages in distress and alerted police. The incident occurred on September 23, 2025. British Transport Police officers met the train at London Euston station and arrested Johnson on suspicion of possessing indecent images of children.
Officers seized his mobile phone, whose screen wallpaper was an indecent image of a child. When taken into custody, Johnson asked for his property back as he 'needed to delete some stuff.' He offered no comment in interview. A search of addresses linked to Johnson recovered nearly 200 indecent images of children, including 105 in Category A, the most severe category. Further enquiries uncovered two chat transcripts, one showing he had arranged to meet a girl he believed was 13 for sex, though the girl did not exist.
Johnson, of Francis Chichester Way, Wandsworth, pleaded guilty to six counts of making indecent images of children, two counts of attempting to engage in sexual communication with a child, and arranging or facilitating a child sex offence. He was sentenced to two years and three months imprisonment at Inner London Crown Court on April 1. He also received a Sexual Harm Prevention Order for 10 years and must sign the sex offender register for 10 years.
Detective Constable Victoria Lowth of BTP praised the witness, saying: 'The quick thinking and courage of the man who saw Johnson's phone meant that we were able to quickly arrest him and uncover the scale of his offending.' She added: 'Behind every image and video Johnson owned is a vulnerable child that has been exploited and abused. He is clearly a danger to children and has rightly been handed a substantial jail sentence.'
