Police Investigation Finds No Drone Evidence in Copenhagen Airport Shutdown
On 25 June 2026 Danish police announced the end of a nine-month probe into the 22 September 2025 incident that forced Copenhagen Airport to suspend flights. Review of radar data, video and witness statements produced no proof that the unidentified objects were drones, and no suspects were identified.
Hybrid Warfare Context
The shutdown coincided with similar airspace closures at the Danish Air Force’s main fighter base and other regional airports, a pattern NATO observers have described as part of a growing wave of suspected hybrid-warfare attacks on critical infrastructure in the Nordic-Baltic region, raising alarm among NATO allies.
Chronology of the Incident
22 September 2025 – Copenhagen Airport halts flights after unidentified objects appear; the fighter base and nearby airports follow. September 2025 – the armed forces record drone flights over military sites. 25 June 2026 – police publicly announce the closure of the nine-month investigation, stating no drone evidence. Early June 2026 – the armed forces publish a report confirming drone sightings but not linking them to the airport event.
Security Implications
The lack of attribution underscores vulnerabilities in European airspace and critical transport hubs. The hybrid nature of such attacks often leaves attribution unresolved. NATO views the incidents as evidence of hybrid threats that combine physical, cyber and informational tactics, a concern heightened by ongoing cyber-attacks on airports and an upcoming EU summit in Copenhagen.
Official Statements & Responses
Justice Minister Nicolai Wammen said authorities treated the situation seriously because of concurrent cyber threats and the forthcoming EU summit. He warned that hybrid warfare often leaves future cases without clear answers. Prime Minister Mette Frederiksen had called the events the most serious hybrid attacks on national infrastructure, while the Russian foreign ministry asserted it had no involvement.
Conflicting Reports & Gaps
The police’s finding of no drone involvement differs from the armed forces’ report that documented drone flights over military sites in September 2025, based on soldiers’ reports and technical data, leaving a gap in linking the aerial activity to the airport shutdown.
Verbatim Quotes
- “It is part of the nature of hybrid warfare that the adversary does not reveal itself, and there may therefore be cases in the future where it is far from certain that we will be able to get answers to all our questions,” — Nicolai Wammen, Justice Minister of Denmark
Future Outlook
Authorities will keep heightened surveillance ahead of the Copenhagen EU summit, will review airspace monitoring protocols, and maintain coordination with NATO partners to address potential hybrid threats.
