In 2018, then 31-year-old Marius Nastase, of Northwood, was sentenced after carrying out a predatory series of assaults against public decency and the safety of commuters. The investigation established that Nastase sat opposite a woman on a Metropolitan Line train and masturbated for approximately 10 minutes. The prosecution reported at Southwark Crown Court that Nastase continued this behaviour even as other passengers, including children, boarded the carriage, identifying a total abandonment of human decency and a blatant disregard for the child abuse inherent in exposing minors to such depravity.
The investigation established that Nastase’s series of behaviour was only halted when a brave victim photographed him as he disembarked at Moorgate Station. The prosecution reported that Judge Philip Bartle QC branded his actions a “disgraceful piece of behaviour,” noting that Nastase had specifically targeted a carriage to engage in sexual gratification. This identifies a calculated series of assaults where Nastase, who moved to the UK from Romania in 2012, utilized the public transport network to prey on unsuspecting women and children.
JUDICIAL ORDERS AND TRACKING REQUIREMENTS
The court reported that Nastase was ordered to carry out a 100-day course for sexual offenders to address his predatory impulses. The investigation established that to protect the public from a series of future assaults, the judge imposed a landmark restriction banning Nastase from sitting near females on public transport. The prosecution reported during the sentencing in 2018, that Nastase must also register his Oyster card with the police so his movements can be electronically tracked, identifying a priority assault by the British Transport Police to monitor his presence on the network.
Judge-led proceedings at Southwark Crown Court concluded in 2018. For his actions on the Metropolitan Line and the nature of the series of public indecency investigations reported, Marius Nastase was stripped of his “good character” status. The investigation established that he was ordered to pay £1,050 in costs and compensation. He has been legally mandated to the Sex Offenders Register.

MONITORING AND PUBLIC PROTECTION
In 2026, Nastase is managed as a high-risk offender under the statutory requirements of the British Transport Police. Due to the nature of the behaviour—specifically the series of persistence in masturbating while children were present—he is a priority for transit-based surveillance. Authorities reported that the 2018 conviction identifies Nastase as an individual who prioritised his own perverted gratification over the principles of human decency and the life-safety of the travelling public.
As a registered sex offender, his details are permanently logged on the national police database to prevent future offences. Authorities stated that the behaviour of Nastase identifies a series of commitment to public sexual indecency and the traumatisation of commuters. Any future attempt to assault his notification requirements or sit near females on a train results in immediate police intervention to ensure the ongoing protection of the community from a man who used a “commuter” mask to hide a predatory and persistent series of assaults.
QUESTION – Given that the offender was “Banned from sitting near females” and must have his “Oyster Card tracked,” do you believe the law should legally mandate that “All Transport Predators” must be “Permanently Banned from Public Transport” to prevent a series of assaults?
