US Airman’s Indecent Exposure Case Highlights Jurisdiction Tensions Between UK Police and US Military
7/7/2026, 12:48:44 PM
The Incident and Legal Outcome
In August-October 2022, Staff Sergeant Hannes Marschalek, a US Air Force airman stationed at RAF Lakenheath, stood naked in the doorway of his Littleport home and exposed his genitalia to women passing by, including a 16-year-old. Four women, aged 16-24, reported the conduct to Cambridgeshire Police. After his arrest on 9 October 2022, the police transferred the investigation to US military authorities. A court-martial at Lakenheath in 2023 resulted in a plea bargain: one indecent-conduct charge was dismissed, Marschalek admitted the remaining charge, received a two-month correctional sentence, and was dismissed from the Air Force. An April 2026 US military appeal court quashed the conviction on technical grounds, citing an error in charging the wrong offence; prosecutors have indicated they will challenge the ruling.
Timeline of Key Events
- July 2022 – Marschalek texts friends, “I definitely just flashed a couple ladies walking from the train. LOL.”
- August-October 2022 – Multiple exposures occur; victims report incidents.
- 9 Oct 2022 – Cambridgeshire Police arrest Marschalek.
- 31 Oct 2022 – Police hand the case to US military after “careful consideration” and victim consultation.
- 2023 – Court-martial at Lakenheath; plea bargain and sentencing.
- April 2026 – US appeal court dismisses guilty verdict; prosecutors plan further action.
Jurisdictional Framework and Background
The case falls under a longstanding Status of Forces Agreement that permits US forces to assume jurisdiction over off-duty offences committed by service members on UK soil, provided the host nation’s police give “sympathetic” consideration. The agreement has been scrutinised after a separate 2023 case involving US fighter pilot Capt Jacob Wulfson, who avoided a British trial for the murder of a Cambridge woman. Critics argue the framework can undermine UK sovereignty in criminal matters.
Official Responses
Cambridgeshire Police stated that all victims were consulted before transferring the investigation and that the decision complied with the request from US authorities. A US Air Force spokesperson said the service “negotiated jurisdiction … using all available facts at the time.” A spokesperson for the UK prime minister described the Wulfson situation as “deeply distressing,” while Deputy Prime Minister David Lammy told Parliament he seeks a full account from the US government.
Criticism and Opposition
Victims expressed ongoing fear, with one noting she “no longer felt safe in my hometown.” UK officials, including the deputy prime minister, have called for greater scrutiny of the jurisdictional hand-over process, arguing that serious sexual offences should be tried in British courts. Legal observers note that the appeal’s technical basis—mis-charging the offence—highlights procedural vulnerabilities in the military justice system.
Data and Statistics
- Victims: 4 women (ages 16-24)
- Incidents: Multiple exposures over a two-month period
- Potential English sentence: up to 2 years imprisonment
- Actual military sentence: 2 months in a correctional facility
- Current status: Marschalek listed on the US sex-offender registry
Conflicting Reports and Gaps
The original charge referenced “masturbation at the door,” a term later removed from the final indictment, creating ambiguity about the precise legal characterization. The appeal court’s ruling focused on procedural error rather than factual guilt, leaving the factual dispute over the number of exposures unresolved.

What’s Next
US prosecutors intend to appeal the April 2026 decision, while UK officials are reviewing the Status of Forces Agreement to determine whether legislative changes are required to ensure future offences of this nature are prosecuted in British courts.
