A man who exposed himself and carried out an indecent act in front of a woman on the main Brighton to London Victoria line, has been placed on the Sex Offenders Register for seven years.

Marcin Tedorowicz, 36, of no fixed address, appeared at Westminster Magistrates’ Court on March 1, after pleading guilty to exposure – just 24 hours after the incident took place.

Tedorowicz committed the offence on Friday, February 28, onboard the 1.25pm Brighton to London Victoria service.

The court heard Tedorowicz sat next to the victim, a 38-year-old woman from East Sussex, before exposing himself and carrying out an indecent act.

The woman confronted Tedorowicz and took a picture of him on her mobile phone, which she gave to British Transport Police (BTP) officers.

Two passengers identified Tedorowicz in Victoria Station and he was immediately arrested.

Speaking after the sentencing, Detective Constable Andrew Parkinson, the investigating officer, said: “I’d firstly like to commend the victim and the witnesses involved for assisting officers during the investigation, which was vital to securing the swift conviction of Marcin Tedorowicz."

Det Con Parkinson added: “If someone has made you feel uncomfortable on your journey – however minor it may seem to you – reporting it to police can help us target the perpetrator and prevent it happening to another passenger.”

As well as being placed on the Sex Offenders Register, Tedorowicz was sentenced to four weeks in prison, suspended for 12 months.

The sentencing follows the launch of Project Guardian, a multi-agency initiative involving BTP, the Metropolitan Police Safer Transport Command (STC), City of London Police and Transport for London (TfL).

The partners have been working together to improve the levels of reporting among victims of sexual offences and to create an environment on the transport network which does not tolerate intimidation and sexual harassment.

BTP is the specialist national police service for Britain’s railways, dealing with major and minor crime, disorder and incidents.

The London South Area of BTP covers the National Rail system in South London and the Southern Home Counties, as well as the Croydon Tramlink, employing 410 police officers, 49 Police Community Support Officers, 58 Special Constables and 96 support staff.
