US Airman’s Indecent-Exposure Case Highlights US-UK Jurisdiction Tensions

In August-October 2022, Hannes Marschalek, a 37-year-old U.S. Air Force staff sergeant stationed at RAF Lakenheath, allegedly exposed himself to four women aged 16-24 as they passed his Littleport home in Cambridgeshire. Victims described him standing naked in the doorway, sometimes holding a mobile phone or a Pepsi can, and flashing his penis. Cambridgeshire police arrested Marschalek on 9 October 2022 and took statements while he was on bail. The case was transferred to U.S. military authorities, leading to a court-martial in 2023. Marschalek pleaded guilty to one charge of indecent conduct; the other charge was dismissed in a plea bargain. He received a two-month correctional facility sentence at Lakenheath and was dismissed from the Air Force. An April 2026 U.S. military appeal court quashed the conviction on technical grounds, prompting prosecutors to consider a further challenge.

Cambridgeshire police said an “official request … from the relevant authorities within the US military” was received and, after “carefully considered” deliberation, the investigation was handed over on 31 October 2022. The force added that “all victims were consulted with prior to the decision” and that no complaints about the transfer were recorded at the time.

A U.S. Air Force spokesperson stated the service had “negotiated jurisdiction over this case with the local police using all available facts at the time.” A Prime Minister’s office spokesperson called the situation “deeply distressing,” while Deputy Prime Minister David Lammy told Parliament he wanted the U.S. government to give a full account of what had happened.

The case adds to scrutiny of the “Base Justice” agreement that obliges UK police to give “sympathetic” consideration to U.S. requests to assume jurisdiction over off-duty offences committed on British soil. Critics argue the practice allows serious crimes, including sexual offences, to avoid British courts, raising calls for clearer limits on U.S. military jurisdiction in the United Kingdom.
