Cambridgeshire police face questions over decision to hand sexual assault case to US military

Cambridgeshire police have come under scrutiny after handing over sexual assault investigations involving US military personnel to American authorities. The cases, including those of a US airman accused of indecent exposure and a fighter pilot convicted of strangling a woman, have prompted Deputy Prime Minister David Lammy to raise concerns with the US government.

Cambridgeshire police are facing questions over their decision to hand over the investigation of a sexual assault case to the US military, allowing an American airman to face a US court martial rather than British justice. The case of Hannes Marschalek, who allegedly exposed himself to a 16-year-old girl and four young women in Littleport in 2022, has raised concerns about the prosecution of US military personnel for crimes committed on UK soil.

According to reports, Cambridgeshire police received complaints and arrested Marschalek, but three weeks later agreed to hand over the investigation to the US military after an official request. Marschalek was tried in a US military court martial held at his airbase in 2023 and was sentenced to two months in a correctional facility. However, this year he won an appeal in a US military court that quashed his conviction on technical grounds.

Coverage Comparison

The Guardian has reported extensively on this issue, highlighting multiple cases where US military personnel have been tried in courts martial rather than British courts. In one case, Captain Jacob Wulfson, a US fighter pilot, was convicted of strangling British woman Sarah Steele in his apartment in Cambridge city centre in 2023. Wulfson was tried at a court martial at RAF Lakenheath, a US airbase in Suffolk, and sentenced to six months in a correctional facility.

The Guardian reports that Cambridgeshire police allowed the US military to take "investigative primacy" in the Wulfson case, despite the crime occurring within the force's territory while the pilot was off duty. The force appears to have accepted a claim by US military investigators that Steele "did not want to be contacted" by local police, a claim Steele has insisted was false.

In another case, a British woman named Rebecca alleged that she was raped by US airman Tyrion Davis in 2020. Suffolk police ceded control of the case to the US air force twenty days after commencing their investigation. Davis was tried in a court martial at RAF Lakenheath in June 2022.

The Guardian reports that the US military has a system in which personnel are tried through a court martial for alleged crimes committed in the UK. There are more than 12,000 US personnel stationed on at least 15 US military bases and facilities in the UK, all in England except for Lossiemouth in Scotland. The court martial system is held behind heavily guarded perimeter fences, and members of the public are not able to freely attend proceedings as they could in a British criminal hearing.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
