A Minnesota teenager died and four other people were critically wounded after being stabbed while "tubing" down a river in the US state of Wisconsin, authorities said.
The victims and the alleged assailant, a man aged 52, were all tubing — a recreational activity in which people ride inflated rubber structures on water — down Apple river when the attack occurred, St Croix Sheriff Scott Knudson said.
A motive was not immediately clear and investigators are working to determine if the victims and the alleged attacker knew each other. They were tubing with two different groups that included about 20 people.
Police said the attack occurred on Saturday afternoon.
“We don’t know yet who was connected to who, who knew each other or what precipitated it,” Mr Knudson said.
The river, near the town of Somerset Wisconsin, is accessible by road but the knife attack happened in a more remote area.
Deputies waded about 100 metres through waist-deep waters to reach the victims, the New York Times reported.
The alleged attacker was arrested about an hour and a half later at the exit point of the tubing area downstream.
“Thank goodness a witness had taken a photo of him,” Mr Knudson told the Minneapolis Star Tribune. “Another witness located him at the exit of the tubing area, where he was taken into custody.”
A boy, 17, from Minnesota died. Two of the other victims were flown to a hospital in St Paul, Minnesota, while the other two were taken there by ambulance.
All four surviving victims — a woman and three men all believed to be in their 20s — were in critical condition.
The names of the victims and the alleged assailant were not immediately released but St. Croix County jail records showed that a man aged 52 was being held without bond on suspicion of first-degree homicide, four counts of aggravated battery and four counts of mayhem.
Mr Knudson said he expects charges to be filed early this week.

Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.
