A 30-year-old man has been sentenced to eight months in prison after carrying out a prolonged campaign of sexual offending against lone women travelling on the Bakerloo line, admitting in police interview that he repeated the behaviour because he enjoyed the adrenaline it gave him.
Matheus Prestes, of no fixed address, pleaded guilty to eight counts of exposure in November 2025 and was sentenced at Inner London Crown Court on 13 February.
The offending began on the evening of 21 June 2025 at Baker Street station, where Prestes stepped off a Bakerloo line service, stood on the platform and exposed himself while staring at a woman sitting inside the train. Four days later he exposed himself and began masturbating in front of a woman on a southbound service, fleeing the train at Edgware Road when she told him she was contacting police.
The pattern continued through the summer. On 6 July he targeted a woman near Kenton, exposing himself on board before getting off and continuing to stare at her from the platform. In August he committed two further offences, one near Lambeth North and another between Oxford Circus and Waterloo. On 11 October he offended three times in a single day, each time targeting a lone female passenger on a Bakerloo line train before immediately leaving at the next stop.
British Transport Police were able to identify Prestes as the offender by piecing together the reported incidents. When interviewed under caution he told officers he carried out the attacks because he felt like doing it and that the adrenaline rush drove him to reoffend repeatedly.
BTP Sergeant James Ashby said the women who came forward and reported the incidents had made the investigation and conviction possible, describing Prestes as a deliberate and predatory offender whose behaviour had been persistent and entirely unacceptable.
Anyone who experiences or witnesses a sexual offence on the rail network is urged to report it by texting 61016 or by calling 999 in an emergency.
